Abstract

Selective laser melting (SLM) using high laser power is a tendency in the future. In this paper, selective laser melting of Cu10Zn alloy using high laser power of 1800 W has been performed. An optimal process parameters are obtained by studying the influence of process parametrs on the density of the SLMed samples. 99.97% relative density is achieved. Furthermore, the performances, such as microstructure, micro-hardness, mechanical properties and conductivity of Cu10Zn parts using optimized parameters were investigated. The results show that the phase composition of SLMed Cu10Zn is only α-Cu, the microstructure is elongated columnar grains which the size of building direction is much larger than that of other direction. A ;〈100;〉 crystallographic texture exists, which results an anisotropy on micro-hardness. Finally, the ultimate tensile strength of 269.2 MPa, yield stress of 203.4 MPa, elongation of 26.4% and conductivity of 43.19%ICAS are achieved for the SLMed Cu- 10Zn parts.
