Titanium alpha and beta phases
WebThus titanium alloys are classified as α, α–β or β alloys, depending on the majority phase in the alloy. It should be noted that often the α alloys may have varying amounts of β phase and likewise β alloys can have small amounts of α phase in them. WebDec 1, 2005 · The effects of α and β phase interactions on the tensile and creep deformation behavior of β titanium alloys was studied using Ti-6.0wt.% Mn and Ti-8.1wt.%V as the model two-phase alloys, and Ti-13.0wt.%Mn and Ti-14.8wt.%V as the single-phase β alloys. The β phase of α-βTi-8.1V deforms by stress-induced hexagonal martensite (α′), while slip and …
