Textural states of a hot-worked MA2-1 magnesium alloy

Quantitative texture analysis is used to study texture formation in an MA2-1 magnesium alloy subjected to axisymmetric upsetting at temperatures of 250–450°C and strain rates of 10^?4–10^{0 ?1}. The deformed structure is examined by optical microscopy, and the results obtained are used to plot the structural-state diagram of the alloy after 50% upsetting. The experimental textures are compared with the textures calculated in terms of a thermoactivation model.     

Determination of the fracture toughness of inhomogeneous three-layer fusion claddings on compact specimens

We propose a method for the evaluation of the fracture toughness (K _1C ) of multilayer fusion claddings on compact specimens at elevated temperatures (20, 70, and 300°C) with cladding (in the slot) of three layers of materials with gradually increasing crack resistance. As the testing temperature increases, the value of K _1C decreases for harder and stronger fusion claddings and, vise versa, increases for less strong and softer materials. __________ Translated from Fizyko-Khimichna Mekhanika Materialiv, Vol. 43, No. 3, pp. 121–122, May–June, 2007.     

Investigation of the Thermal Conductivity of Methanol–n-Hexanol Mutual Solutions at High Parameters of State

The thermal conductivity of methyl and normal hexyl alcohols and of methanol–n-hexanol solutions in wide ranges of temperature and pressure are measured in a facility implementing the regular regime method. The regularity of variation of the thermal conductivity of binary solutions with concentration is found.

Filtration drying kinetics of gas-permeable articles

The drying process under conditions of filtration of a drying agent through a porous structure of a moist article is considered. The existence of three dehydration stages is established: 1) mechanical displacement of water; 2) elimination of moisture in the form of a gas-liquid emulsion; 3) drying. A kinetics equation is derived for each stage. Combination of all the three stages provides a high rate of the total process exceeding the drying rate by tens of times when flowing around an object as a unit.L'vov Polytechnic Institute.
