“…Therefore, in the framework of the approach, transformation of alloys in the Cr-Ti-V system in high-entropic alloys, it is of interest to research what influence additional Mn alloying can exert on structuralphase states of one-phase alloys (Cr, Mn, Ti, V,) in a disordered state based on the BCC lattice. Earlier to search for regularities when studying peculiarities of structural and phase states in binary and ternary systems, the authors used an approach based on analysis of crystal-geometric and crystal-chemical characteristics of metallic compounds and solid solutions [12][13][14][15]. The purpose of this paper is to present the results of researching the features of structural and phase states in ternary Cr-Ti-V and Cr-Mn-V systems based on the analysis of binary state diagrams, forming them, and crystal-geometric and crystal-chemical factors.…”
