TLDR
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.About:

Quenching and partitioning martensite-a novel steel heat treatment
TL;DR: In this paper, a novel concept for the heat treatment of martensite, different to customary quenching and tempering, is described, which can be used to generate microstructures with martensites/austenite combinations giving attractive properties.
