Corrosion Behavior of the S136 Mold Steel Fabricated by Selective Laser Melting
TL;DR: In this article, the microstructure, hardness and especially corrosion behavior of the samples fabricated by selective laser melting (SLM) and casting were investigated, and XRD results exhibit that the γ-Fe phase is only obtained in the SLM parts, and the α-Fe peak slightly moves to low diffraction angle compared with casting counterparts.
