Deformation Behavior of an Age-Hardenable Beta+Alpha-Two Titanium Alloy

Abstract

The beta Titanium alloy Ti-23niobium-11aluminum (at. pct.) differs from other beta Ti alloys in that it is age-hardenable due to the formation of lath-like, alpha-two precipitates based on Ti3Al. This study reports the room temperature deformation and slip behavior of the Ti-23Nb-11Al alloy as a function of heat treatment. The results indicate that the formation of the alpha-two precipitates results in not only a large increase in yield stress but also can induce a change in slip mode from inhomogeneous to uniform slip.
