摘要：
Al-12Si components were manufactured by Selective Laser Melting (SLM) using three different atmospheres: argon; nitrogen and helium. The atmosphere type did not affect the part's density or hardness and all components reached near full relative density (> 97%). The mechanical properties of the components produced in Ar and N-2 were superior to those in He, especially the ductility, which has been attributed to the formation of pore clusters in the microstructure. The mechanical properties in SLM-produced components are superior to those produced using conventional method. Crown Copyright (C) 2014 Published by Elsevier B.V. All rights reserved.
