Triple titanium aluminide-based diagrams. Analysis and construction

Abstract

Based on ordering the condition diagrams Ti-Al-Me (Me=V, Cr, Mn, Fe, Co, Ni, Cu) the authors have determined the reduction of homogeneity areas sizes in firm solution on the basis of beta-Ti among the alloying elements V-Cr-Mn-Fe-Co-Ni-Cu with the growth of a number of intermetallic compounds inside the isothermal triangle. It is revealed that almost all "internal" compounds possess a cubic or hexagonal syngony.
