Abstract Aluminum alloy with small density，high specific strength properties received extensive attention and
application.Composites prepared by powder metallurgy have some advantages：flexible alloy composition design，
tiny and homogeneous microstructure. Compared with the composites prepared by ordinary smelting method，the
composites with powder metallurgy have more excellent mechanical properties and were used more widely. This
paper introduces the internal and overseas research status about powder metallurgy aluminum alloys，the process
about the preparation and consolidation of powder and post-processing technology. Meanwhile the characteristics
and effects of each process were analyzed，especially several kinds of forming technologies. Otherwise，On the basis
of the powder metallurgy，the development of powder metallurgy aluminum alloy-graphene and the development
trend of powder metallurgy is briefly introduced.
