Tungsten ore doped Al/Cu alloy powder compact was processed by laser combustion synthesis (CS). Optical microscopy (OM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to study the effect of laser processing and pressing pressure on microstructure and density of the alloy. The results show that the compactness increases, the microstructure is refined and the uniformity is promoted within a certain range. As the relative density increases, the densification of the product increases. The sintered alloy is mainly made from matrix phase of higher toughness mixed up with intermetallic compounds of high dispersion, and nanocrystals, which is compound texture.
