Excerpt

Quenching and partitioning (Q&P) steel is a term used to describe a series of C–Si–Mn, C–Si–Mn–Al, or other steels subjected to the recently developed Q&P heat treatment process. The purpose of Q&P steel in the context of automotive structures is to obtain a new type of ultrahigh-strength steel with good ductility to improve fuel economy while promoting passenger safety. With a final microstructure of ferrite (in the case of partial austenitization), martensite, and retained austenite, Q&P steel exhibits an excellent combination of strength and ductility, which permits its use in a new generation of advanced high-strength steels (AHSS) for automobiles. While autobody application represents the first implementation of Q&P on an industrial scale, the heat treatment concept is also applicable to a range of other potential applications. …
