Optimization of the Q-P Process Parameters for Low Alloyed Steels with 0.2% C

open access: yesArchives of Metallurgy and Materials, 2014
In steels which are treated by the quenching and partitioning (Q&P) process, carbon content is one of the crucial parameters because carbon contributes greatly to stabilization of retained austenite and strengthens the material. In the present study, the

Q&P PROCESS IN PRESS-HARDENING OF 42SICR STEEL [PDF]

open access: yesActa Metallurgica Slovaca, 2018
One of today’s advanced heat treatment routes for high-strength steels is the Q&P process which delivers high ultimate strengths combined with good ductility. The resulting microstructure is a combination of martensite and small fractions of bainite and retained austenite. Retained austenite has the form of thin needles adjacent to martensite laths.
