Abstract

Abstract

A part of Al-Ti-Mo-Cr quaternary phase diagram is constructed for the microstructure control of DO₂₂-Al₃Ti or its derivative, Ll₂-(Al,Cr)₃Ti, -based alloys. It was found that quaternary bce phase equilibrates with either DO₂₂-Al₃Ti or Ll₂-(Al,Cr)₃Ti, or both, exist in large compositional areas. The mechanical properties is strongly affected by precipitates appearing, and presumablyalloy microstructures.
