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