摘要：

The microstructure stability of Al3Ti/Al alloy prepared by mechanical alloying (MA) was investigated in the simulating environment where they may be used. The results show that the MA alloy possesses fine microstructure (the grain size is about 0.5μ). After cycling loaded followed by heat exposure at 350°C for 24 h, no microstructure coarsening of the alloy occurred, which means that the Al3Ti/Al alloy behaves good microstructure stability at high temperature. The compression yield strength of the alloy reaches up to 247 MPa at 350°C.
