Effect of Post-Heat Treatment on the AISI M4 Layer Deposited by Directed Energy Deposition

Effect of Post-Heat Treatment on the AISI M4 Layer Deposited by Directed Energy Deposition

Currently, high-speed steel (HSS) powders are deposited locally on a metal surface through direct energy deposition (DED) onto hardface tool steel. Although the HSS powder enhances the hardness and the abrasion resistance of a metal surface, it makes the tool steel brittle because of its high carbon...
