Martensitic steels via laser powder-based additive manufacturing: Recent advances in process parameters, microstructure tailoring, and mechanical performance

Materials & Design
Ferrous alloys, as foundational structural materials, hold great promise for metal additive manufacturing (AM). Among them, martensitic steel (MS) has attracted attention in laser powder based-AM due to its high strength, excellent hardenability, and ...

Gaseous surface hardening of martensitic stainless steels

, 2018
The present work addresses heat and surface treatments of martensitic stainless steel EN 1.4028. Different combinations of heat treatments and surface treatments were performed: conventional austenitisation, cryogenic treatment and in particular high temperature solution nitriding (HTSN) and low temperature surface hardening (LTSH).
