Q-P Process Optimization With the Use of Quenching Dilatometer

Popis výsledku v původním jazyce

The current efforts in production of low-alloyed steels are aimed at achieving high ultimate and yield strengths, while maintaining sufficient elongation and good weldability in these materials. Among advanced heat treatment processes capable of reachingthis goal, there is also the Q-P process (Quenching and Partitioning). The process consists in rapid quenching between the Ms and Mf temperatures in order to prevent full martensitic transformation. The immediately following heating leads to tempering of the martensite and to diffusion of excess carbon from martensite to retained austenite. The aim of the Q-P process is to produce very fine martensite microstructure with retained austenite between martensite plates. The experimental programme was carried out on a high-strength low-alloyed steel containing 0.2% carbon and a higher amount of silicon about 1.5%. Higher silicon content in the microstructure contributes to stabilization of retained austenite by suppressing formation of carb
