Ti and Al

Zr intermetallic compounds enhanced phases are generated in the aluminum matrix.The Vickers hardness of the composites are increased from85.7 HV to 118.1 HV with the sintering temperature increased from 700 ℃to 900 ℃.The composites prepared by sintering at 800℃ present the acceptable tensile strength of 140.71 MPa and yield strength of 40.5 MPa.
