Abstract

Abstract

The precipitaion of Al₂Ti induced by strain was studied by means of stress-relax method during deformation of Ll₂ structure Al₃Ti(+9.7Fe) alloy.It is shown that the Al₂Ti precipitatings is the principal reason for the ductile fracture of Al₃Ti base alloy at room or middle temperature.By TEM,it is proved that the Al₂Ti precipitation has rigorous crystal orientation relationship with Al₃Ti matrix,{100}_p//{100}_m.
