PROCEDURE FOR POST-HEAT TREATMENT OF ALUMINIUM-SILICON-MAGNESIUM COMPONENTS MADE BY SELECTIVE LASER MELTING (3D METAL PRINTING)

摘要

The heat treatment of a component made of an Al-Si-Mg alloy by an SLM process comprises subjecting the component to a stress relieving heat treatment, without sintering loose powder entrapped with or within the component, prior to cutting the component from a build platform on which the component was made by the SLM process. The stress relieved component then is separated from the build platform, and then subjected to solution heat treatment to take solute elements and phases into solid solution and quenched and artificially aged.
