Abstract: Tungsten/Al-Cu powder compacts with different tungsten powder contents were synthesized by laser combustion. The influences of tungsten powder content on the microstructure, densification and hardness of tungsten/Al-Cu composite were studied by SEM, OM, XRD and Vickers hardness tester. The results show that doped tungsten powders can refine alloys structure, increase the uniformity of alloys and promote densification. When the mass ratio of doped tungsten powder to Al-Cu powder is 3%, the synthesized density and hardness of sample reach the highest values, i.e. 3.43 g/cm³ and HV 244.4.
