In situ heat treatment in selective laser melted martensitic AISI 420 stainless steels
TL;DR: In this paper, the authors explored an evolution of a microstructure in AISI 420 martensitic stainless steel during selective laser melting and found that during manufacturing a partitioning and austenite reversion took place, owing to the thermal cycling of the inner regions during manufacturing.
