Effect of Heat Treatment of 316L Stainless Steel Produced by Selective Laser Melting (SLM)
Selective Laser Melting (SLM) shows a big potential within additive manufacturing of
metals. The competitive mechanical properties compared to conventional processes as well as the
geometry freedom are the main advantages of SLM. 316L stainless steel has been investigated in
previous works regarding microstructure and mechanical properties. However, the influence of
heat treatments has not been fully reported yet. This work studies the influence of different heat
treatments applied to 316L stainless steel produced by SLM. The microstructure evolution was
investigated for different conditions. Tensile, Charpy and hardness tests were performed on the as
built and heat treated samples.Mechanical Engineerin
