摘要：

The microstructure and mechanical properties of rapidly solidified Al93Mn5Ce1M1 (M = Cr, Mn, Fe, Co, Ni, Pd or Cu) alloys were examined with the aim of obtaining a high specific strength alloy by structural control in a mixed structure consisting of nanoscale icosahedral particles surrounded by Al phase. The as-quenched structure consists of spherical icosahedral particles and equiaxed Al grains with icosahedral precipitates along the grain boundary for the Al93Mn5Ce1M1 (M = Ni, Co or Fe) alloys and the highest value of sigma(f) is 1160 MPa for the Ni-containing alloy. The reasons for the formation of the novel mixed structure and the achievement of high sigma(f) and good ductility have also been investigated on the basis of the present results and the previous data reported by the present authors.
