The effect of heat treatment on the microstructure and mechanical properties of 3D-printed AlSi9Cu3Fe alloy
Original language description
In this paper, we characterize AlSi9Cu3Fe alloy prepared by selective laser melting (SLM), a 3D printing technique based on the localized melting of a powder material by a laser beam in thin successively deposited layers. The layer-wise building-up resulted in an anisotropic and hierarchical microstructure of this alloy. High cooling rates brought a very fine microstructure, which contributed to high material strength, but also residual stresses, which are undesirable. Residual stresses can be reduced by various heat treatments. We carried out stress-relief and T6 heat treatments and studied their effect on the microstructure and mechanical properties. T6 heat treatment brought a significant increase in tensile yield strength.
