Effect of thermomechanical treatment on the crack resistance of titanium alloys

Conclusion The optimal thermomechanical treatment of dual-phase titanium alloys, which contributes to their improved crack resistance, consists of deformation in the lower portion of the -region+deformation in superplasticity regimes+quenching from the deformation temperature+aging. In this case, maximum hardening is also achieved.A. A. Baikov Institute of Metallurgy. Translated from Metallovedenie i Termicheskaya Obrabotka Metallov, No. 5, pp. 49–50, May, 1990.     

Influence of Calcium Phosphates on the Morphology and Properties of Polylactide Composites

Materials Science - We developed polylactide composite materials with calcium-containing fillers; in particular, calcium orthophosphate and calcium hydroorthophosphate. It is shown that the degree...     

Effect of the chemical structure of hexenyl succinic acid esters – the foundation of synthetic oils – on their dynamic viscosity

The correlation between the dynamic viscosity and chemical structure of hexenyl succinic acid esters is investigated in a wide temperature range from −30 to +10 °C for different rotation frequencies.     

Determination of Se,As, Sb,Te, and Bi in wastewaters of mining-and-processing integrated works with the use of AAS-ETA

The procedure of analysis of wastewaters of mining-and-processing integrated works on the content of Se, As, Sb, Te, and Bi with the use of an atomic absorption method with electrothermal atomizer, which involves the preliminary sample preparation and choice of temperature program, modifier, and corrector of nonselective absorption, was described. The conditions were matched for the determination of low concentrations of these elements in natural waters.
