Q-P Processing of High-Strength Low-Alloyed Steel Sheets

Popis výsledku v původním jazyce

Availability of high-strength sheets with good ductility at reasonable cost is not sufficient on the European market. In the present work, the QP effect (Quenching and Partitioning) was used to obtain thin sheets with high strength and good ductility. The experiment was performed on low-alloyed steel containing 0.2% carbon and a higher amount of silicon of about 1.5%. The material was rolled into 1 mm thick sheet. This grade of steel is a cost-effective material thanks to its low amount of alloying elements. This group of low-alloyed steels, if heat treated or thermomechanically treated in a suitable manner, offers a favourable combination of strength, elongation and toughness. The QP process consists in rapid quenching of the material between Ms and Mf temperatures to prevent the martensitic transformation from propagating through the entire volume of the workpiece. Subsequent heating causes diffusion of excess carbon from martensite to retained austenite, thereby increasing the stabi
