Abstract

Abstract:

A multi-component copper-based metal powder, which consists of Cu, Cu-10Sn, and Cu-8.4P, is developed. Selective laser sintering of this powder system is processed through the mechanism of liquid phase sintering. The effects of powder characteristics such as particle shape, size distribution, chemical composition, component ratio, and dispersion homogeneity on the densification and the resultant microstructures are investigated.
