Our study highlights physical and chemical conditions for titanium aluminizing of alloys in the closed reactionary space in the chlorine medium at low pressure. In addition, we+ show that simultaneous saturation of alloys by titanium and aluminum is possible in a wide range of saturated elements densities in the original mixture. Finally, we consider phase and chemical compositions, the structure of diffusion layers, formed on the technical iron after titanizing, nitriding with further titanizing, and titanium aluminizing.

Utilizing blends based on hydrogenated titanium powder with various alloying powders, we synthesize Ti-5Al-5V-5Mo-3Cr alloy. Moreover, we argue for the fact that the complex Al-V-Mo-Cr master alloy and the combination of Al-V master alloy with Mo and Cr are the best types of alloying powders since they allow reaching chemical and microstructure homogeneity as well as relative density up to 98 %. We further analyze the parameters affecting mechanical properties of synthesized alloy and obtain mechanical properties sufficient for practice application of synthesized alloy. [ABSTRACT FROM AUTHOR]
