Quenching and Partitioning (Q&P) Processing of Martensitic Stainless Steels

, 2018
Austenite was stabilized in the martensitic stainless steel grade AISI 420 by means of quenching and partitioning (Q&P) processing. The effects of quenching temperature on the microstructure and mechanical properties were investigated.
