摘要
A part of Al-Ti-Mo-Cr quaternary phase diagram is constructed for themicrostructure control of D0_(22)-Al_3Ti or its derivative, L1_2-(Al,Cr)_3Ti, -based alloys. It wasfound that quaternary bcc phase equilibrates with either D0_(22)-Al_3Ti or L1_2-(Al,Cr)_3Ti, orboth, exist in large compositional areas. The mechanical properties is strongly affected byprecipitates appearing, and presumably alloy microstructures.
