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

Experimental and Numerical Process Design for Press Partitioning of the New Q&P Steel 37SiB6
Quenching and partitioning (Q&P) heat treatments of low-alloy steels with exceptional property combinations are particularly promising. In this study, we characterize for the first time a new low-alloy steel to be processed using Q&P heat treatments.

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