Symposium Additive Manufacturing of Metals: Establishing Location-Specific Processing-Microstructure-Property Relationships
Presentation Title Anisotropic Mechanical Behavior of AlSi10Mg Parts Produced by Selective Laser Melting
Author(s) Ming Tang, Petrus Christiaan Pistorius
On-Site Speaker (Planned) Ming Tang
Abstract Scope As one metal additive manufacturing process, selective laser melting (SLM) is usually accompanied by the development of anisotropy, which arises from sample geometry and building orientation. To date, there have been only a limited number of studies on this topic. In this work, anisotropic behavior of AlSi10Mg parts produced by SLM was investigated by performing tension and fatigue tests, employing microscopy to examine the internal porosity and microstructure development at the fracture surface, and nanohardness measurements to quantify the local decrease in strength. The results shows that Z-oriented samples have appreciably lower ductility and shorter fatigue life, and tearing along the coarser heat-affected zone is observed. The coarser solidification microstructure at the heat-affected zone is responsible for the loss of ductility, and porosity distribution brought by the laser scanning strategy dominates orientation-dependent performance during fatigue tests.
