Bulk high strength and thermally stable Al85Nd8Ni5Co2 samples have been prepared by selective laser melting (SLM). The alloy shows a composite-like microstructure consisting of submicron-sized stable intermetallic phases dispersed in an Al matrix, which leads to high compressive strength (1-0.5GPa) at elevated temperatures (303-573K). These results indicate that SLM is an effective alternative to conventional routes for producing dense, thermally stable and near net shaped components from high strength Al-based alloys.
