Selective laser melting (SLM) is a popular powder bed fusion technique used for manufacturing of metal parts. Due to its high-energy laser heat source, SLM process creates a high thermal gradient and fast cooling rate. As a result, it tends to generate a fine microstructure with high dislocation den...
