Abstract:

Phase equilibria have been determined for Ti-V, Mo, Cr system with Cr additions up to 10 wt pct. The results indicate composition ranges where the equilibrium phase is beta, as-cast alloys are ductile enough to be cold worked and where the tendency to lose ductility during heat treatment due to oxygen segregation is minimal. An investigation of the effect of adding Al and Si to beta alloys indicates that yield stress and Youngs modulus are increased while density and ductility are decreased. It appears that Al increases the ductile brittle transition temperature. Author
