A physical model of carbide formation with vacuum carburizing is developed with the aim of controlling complexly-alloyed steel diffusion layer structure, taking account of excess phase formation of both the cementite type, and special carbides. A mathematical model is developed on the basis of the physical model adopted, adequate for experimental results. Analysis of calculated results is used as a basis for demonstrating the effect on carbide formation of alloying with chromium and strong carbide-forming elements, and also production factors. © 2013 Springer Science+Business Media New York.

Isothermal and thermokinetic diagrams are worked out for the decomposition of supersaturated solid solution of for heat treated alloy V91 of the Al - Zn - Mg - Cu system. Curves for these diagrams correspond to the start of forming GP zones, metastable T' and stable phases (T,η). An isothermal diagram for the alloy is plotted from the results of hardness and corrosion rate determination. Critical cooling rates are determined for alloy V91 from the diagrams obtained. © 2010 Springer Science + Business Media, Inc.
