Q&P PROCESS IN PRESS-HARDENING OF 42SICR STEEL
Acta 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.

Decarburization effects on high-cycle fatigue of uncoated press hardened steels
Materials Testing, 2023 Abstract The decarburization layer can be detrimental and lead failures in press hardened steels. This work investigates the effect of decarburization layer on the fatigue crack origination and growth on press hardened parts of uncoated 22MnB5 steel. The decarburization layer was analyzed by light microscope, scanning electron microscope,
