The Friction Stress of the Hall–Petch Relationship of Pure Mg and Solid Solutions of Al,Zn, and Gd

Temperature and solute concentration effects on the friction stress, σ_o, of cast (texture-free) polycrystals of pure Mg, and of Mg-Al, -Zn and -Gd binary solid solutions are discussed using phenomenological arguments. The temperature effects on the pure metal suggest that σ_o relates to the ratio between the CRSS of prism and basal slip, against early suggestions that it should only relate to the CRSS for basal slip. Solid solution softening upon prism slip accounts for the minima in σ_o at ~ 0.5 at. pct in Mg-Zn and Mg-Gd alloys. In the concentrated alloys, solute-specific hardening effects upon slip and twinning lead to diverging behaviors: in Mg-Al and Mg-Zn, σ_o remains below that of pure Mg. Strong short-range order by Gd leads to a steep monotonic increase, and to a value larger in compression than in tension due to the activation of {10-11} twinning at high concentrations. The negative σ_o of the dilute Mg-Zn alloys is an artifact created by the tension/compression asymmetry stemming from the polar character of {10-12} twinning.

Investigation into the Formation of Texture,Microstructure, and Anisotropy of Properties during Rolling Sheets of the Aluminum–Lithium 1420 Alloy

Results of investigations into the formation of the crystallographic orientation of the structure and anisotropy of properties during rolling sheets of the aluminum–lithium 1420 alloy of the Al–Mg–Li system are given. Hot-rolled billets of the 1420 alloy were cold-rolled with intermediate quenching according to the following schedule: 7.3 mm → 4.8 mm → 3.0 mm → 1.8 mm. The samples were selected after each passage to perform mechanical testing and analyze the structure using optical microscopy and diffractometry. A deformed fibrous structure and considerable anisotropy of mechanical properties is characteristic of sheets of all considered states. Herewith, the maximal plasticity is observed at an angle of 45° to the rolling direction. The character of anisotropy of properties formed at the hot-rolling stage is not varied during cold rolling. Sheets of the 1420 alloy have a sharp deformation texture at all rolling stages due to the conservation of the unrecrystallized structure. For example, when analyzing pole figures and preferential orientations, an increase in volume fractions of rolling texture is revealed (the slow one of the brass type and more rapid of the S type) with the rise of summary deformations of cold rolling. The recrystallization texture (of the R type) is present in small amounts only after hot rolling. The volume fraction of the texture-free component decreases with an increase in summary deformations. It is concluded based on these results that, in order to decrease the fraction of the deformation texture and lower anisotropy of properties in sheets of the 1420 alloy, it is first and foremost necessary to provide the running of recrystallization at the hot-rolling stage in order to fabricate the recrystallized hot-rolled billet for subsequent cold rolling.     

Application of physical–empirical models to calculate a fragment of the phase diagram and the physical properties of bcc Fe–Cr alloys: II. Calculation of phase boundaries,spinodal, and the temperature dependence of the heat capacity of an alloy

The contributions at a temperature of 500 and 600 K of the chemical, elastic, vibrational, magnetic, electronic, and configurational energies to the Gibbs energy of mixing of bcc alloys without regard for the contribution of a short-range order are calculated as functions of composition and temperature using physical–empirical models. The temperature dependences of the heat capacity of an alloy in both one- and twophase states are calculated. The heat capacity jumps calculated for alloys of various compositions can be used to estimate the equilibrium solubility boundaries of Fe–Cr alloys, which can hardly be found from experimental data because of the slow diffusion processes that occur when an equilibrium state is reached. The calculated solubility boundary of bcc solid solutions and the spinodal and the heat capacity of Fe–Cr alloys are compared with the experimental data and the calculation results obtained in other works. The agreement and discrepancy between these data are discussed.

The effect of conditions of preparation on the strength of WC — Co hard alloys and the relationship between the strength of these alloys and their structure and composition

Conclusions This paper presents a review of investigations which elucidated the effect of the technological conditions of obtaining the initial tungsten powder and the grinding and sintering conditions on the strength of a hard alloy during bending. An analysis of the results of these investigations shows that the differences in the strength of alloys differing in carbide grain size is primarily due to various manufacturing conditions and not to differences in grain size.On applying various methods of regulating the size of the carbide grain, sharply different changes in alloy strength are observed. The influence of the size of the grain was not noted, since it was suppressed by the greater effect of the technological factors.On excluding the effect of changing the sintering temperature (and other variable technological factors) the dependence of the alloy strength on the cobalt content changes its form: the maximum strength between 15 and 25% cobalt, noted in many researches, is not observed in this case. The strength increases continually up to 50% cobalt.The dependence on grain size with various methods of regulating carbide dispersity, and the dependence of the strength on the cobalt content on excluding the effect of the technological factors differ substantially from the regularities described by Gurland [1].The theoretical theses of Gurland are ungrounded, inasmuch as the strength relations are at variance with them, when the effect of the technological factors is excluded.The relations actually existing may be explained on the basis of the skeleton structure of the carbide and cobalt phases.

Axial stresses and texture development during the torsion testing of Al,Cu and α-Fe

Polycrystalline samples of Al, Cu and α-Fe of commercial purity were tested in torsion over the temperature range 20–400, 500 and 800°C, respectively. The axial forces induced were measured: at low temperatures and small strains, these were compressive in all three metals; as the temperature and strain were increased, they dropped to small compressive values (Al), or became tensile (Cu and α-Fe). The textures developed were also determined: at low temperatures and small strains, the {11̄1̄} 〈110〉/{1̄11} 〈1̄1̄0〉 set predominated in the Al, was present in conjunction with the {1̄12} 〈110〉/{l1̄2̄} 〈1̄1̄0〉 set in the Cu and the two sets {112̄} 〈111〉/{1̄1̄2}〈111〉 and {011̄}〈111〉/{OT1K111} were observed jointly in the α-Fe. As the temperature and strain were increased, the {1̄12} 〈110〉/{11̄2̄} 〈1̄1̄0〉 set became progressively more dominant in the Al; it, together with the {11̄1̄} 〈110〉/{1̄11} 〈1̄1̄0〉 in the Cu; and the single {1̄1̄2} 〈111〉 component in the α-Fe. Depending on the temperature and strain range, the individual ideal orientations are observed to be rotated about the r axis parallel to, or in the sense opposite to, the shear. It is shown that compressive axial stresses are associated with the rotation of {001} 〈110〉 in the sense of the shear, or with the rotation of {11̄1̄} 〈110〉/{1̄11} 〈1̄1̄0〉 in the sense opposed to the shear. Conversely, tensile axial stresses are associated with shear oriented rotations of the {11̄1̄} 〈110〉/{1̄11} 〈1̄1̄0〉 combination.     

Structure and thermal properties of the matte of the autogenous smelting of copper–zinc concentrates

The phase composition and the structure of the solidified mattes of the autogenous smelting of copper–zinc concentrates containing 49.8 and 61.0% Cu in Vanyukov’s furnace are studied. The forms of the main elements (Cu, Ni, Fe, S, O) and the accompanying impurities (Zn, Pb, As, Sb, Co, Sn, Au, Ag) in the rich matte are determined. The phase-transformation temperatures in cooling of the mattes in an inert or oxidizing gas atmosphere are found.     

Effect of heat treatment on the phase composition,the texture,and the mechanical properties of a V1461 (Al–Cu–Li) alloy

The heterogeneity of the phase composition, the texture, and the mechanical properties in various zones and directions of plates (thickness T = 80 mm) in a V1461 (Al–Cu–Li) alloy has been studied. It is noted that the strength characteristics are maximal in the median cross section (ultimate strength and yield strength are 570 and 540 MPa, respectively); in the cross section at 0.25T, these values are 530 and 490 MPa, respectively; in the height direction, they are only 490 and 440 MPa. The studies of texture show that an intense one-component texture, which is similar to the matrix and δ' phases, is observed in a medium plate layer of thickness (0.3–0.35)T; the {011} texture plane is parallel to the plate plane with the dominant “brass” {110}〈112〉 texture. Hardness is shown to increase from HRB70 after aging at 120°C for 20 h to HRB85 after three-step aging at 120°C, 20 h + 140°C, 24 h + 150°C, 24 h. It is shown that aging at 120 and 140°C is accompanied by the precipitation of the Θ' phase along with the δ' phase, and aging at 150°C also leads to the precipitation of the T₁ phase.     

Why did the sperm cross the cumulus? To get to the oocyte. Functions of the sperm surface proteins PH-20 and fertilin in arriving at, and fusing with, the egg

The sperm surface has an active role in the events of fertilization. The definition of the sperm surface in both its composition and domain organization begins during spermatogenesis and continues until the moment of sperm-egg fusion. Alterations of the surface proceed as a result of internal programming and environmental cues from both the male and female reproductive tracts, including interactions with the egg itself. We have investigated the sperm surface to understand its domain organization and the ongoing changes in this organization as well as the role of specific surface proteins in fertilization. Much of our research has concentrated on two surface proteins: PH-20 and fertilin. PH-20 is a single-chain protein, anchored in the membrane via a glycosyl phosphatidylinositol (GPI) anchor. The N-terminal domain of the molecule has a hyaluronidase activity. The hyaluronidase activity of PH-20 on the sperm plasma membrane enables sperm to penetrate the layer of cumulus cells surrounding the oocyte. PH-20 has a second function, unrelated to its hyaluronidase activity, in the binding of acrosome-reacted sperm to the zona pellucida (secondary sperm-zona binding). The fertilin molecule is an alpha,beta heterodimer whose two subunits are closely related transmembrane proteins. Fertilin beta has a disintegrin domain that has high sequence homology with the snake disintegrins, a known class of soluble integrin ligands. The binding site of the beta disintegrin domain functions to bind sperm to the egg plasma membrane via a mechanism that leads to sperm-egg fusion. The precursor of fertilin alpha, made in the testis, has an active metalloprotease site that could function in spermatogenesis. This metalloprotease domain is removed by proteolytic processing in the testis. Mature fertilin alpha on sperm also has a hydrophobic, putative "fusion peptide" that may promote the process of lipid bilayer fusion between sperm and egg plasma membranes. Fertilin alpha and beta are the first identified members of a new gene family of transmembrane proteins, the ADAM family, so called because they contain A Disintegrin And Metalloprotease domain. Many distinct ADAMs have now been found in diverse tissues and species (Drosophila to human) and are proposed to have a variety of functions in development and the adult. In addition to fertilin, other ADAMs are also present on the sperm plasma membrane and may participate with fertilin in sperm-egg fusion.     

Phase composition,texture, and anisotropy of the properties of Al–Cu–Li–Mg alloy sheets

The formation of the anisotropy of the mechanical properties, the texture, and the phase composition of thin-sheet Al–4.3Cu–1.4Li–0.4Mg and Al–1.8Li–1.8Cu–0.9 Mg alloys have been studied by X-ray diffraction and tensile tests. Various types of anisotropy of the strength properties of the alloys have been revealed: normal anisotropy (strength in the longitudinal direction is higher than that in the transverse direction) in the Al–4.3Cu–1.4Li–0.4Mg alloy and inverse anisotropy in the Al–1.8Li–1.8Cu–0.9Mg alloy. It is shown that the anisotropy of the strength properties is dependent not only on the texture of a solid solution, but also on the content and the texture of the δ' (Al₃Li) and T1 (Al₂CuLi) phases and their coherency and compatibility of deformation with the matrix.     

Metal-organic frameworks of lanthanide iminodiacetates and tartrates:Synthesis,structural characterization and luminescence properties——Commemorating the 100th anniversary of the birth of Academician Guangxian Xu

Two series of lanthanide-containing metal-organic frameworks(Ln-MOFs) of the general formula{[Ln(HIDA)_2 H_2 O]ClO_4·H_2 O}_n(Ln = La(1),Nd(2),Eu(3),Gd(4),Tb(5),Eu:Tb(6);H_2 IDA=iminodiacetic acid) and [Ln(TT)(HTT)(H_2 O)_3]_n(Ln=Eu(7),Gd(8),Tb(9),Dy(10),and Eu:Tb(11);H_2 TT=tartaric acid)were synthesized by reacting Ln(ClO_4)_3 with iminodiacetic acid and L-tartaric acid,respectively.All compounds were structurally characterized by single-crystal X-ray diffraction.Elemental analyses are co nsistent with the corre sponding crystallographically generated formulas.Mo reover,the luminescence properties of both the single and mixed-lanthanide complexes were studied.Near infrared,red,and green emissions that are characteristic of Nd(Ⅲ),Eu(Ⅲ),and Tb(Ⅲ) are observed for 2,3/7,and 5/9,respectively.For the two mixed-lanthanide complex systems 6 and 11,depending on the relative amount of Eu(Ⅲ) and Tb(Ⅲ),the color of emission can be fine-tuned.It is found that a small amount of Eu(Ⅲ) is adequate for the observation of the most intense transition of Eu(Ⅲ).This is believed to be a result of energy transfer from Tb(Ⅲ) to Eu(Ⅲ) within the same complex-a conclusion supported by the significantly shortened lifetime of Tb(Ⅲ) and the accompanying enhanced lifetime of Eu(Ⅲ) in the mixedlanthanide complex with respect to the corresponding values for the pure Tb(Ⅲ) and Eu(Ⅲ) complexes with the same ligand.
