Phase Transformations in the Quenched Alloy Based on Orthorhombic Titanium Aluminide during Heating

Phase transformations in the alloy based on the orthorhombic titanium aluminide (Ti-24,3Al-24,8Nb-1,4V-1,0Zr-0,6Mo-0,3Si – at. %) were studied by differential thermal analysis. The alloy was quenched from the different phase regions (β+O, β+O+α2+(Vω), β+α2, β) and was subjected to continuous heating...

Summary:Phase transformations in the alloy based on the orthorhombic titanium aluminide (Ti-24,3Al-24,8Nb-1,4V-1,0Zr-0,6Mo-0,3Si – at. %) were studied by differential thermal analysis. The alloy was quenched from the different phase regions (β+O, β+O+α2+(Vω), β+α2, β) and was subjected to continuous heating up to . It was found that the heating temperature of the O-alloy, which determines its phase state during quenching, affects the temperature ranges, intensity, and stages of the phase transformations during subsequent heating.
