| Description
| - New procedures of heat treatment make it possible to obtain a combination of very good tensile strength and great ductility for low alloyed high strength steels. Three treatments utilizing the metastable austenite component for improving steel formability have been developed for their unconventional processing. These are intercritical annealing typical for TRIP steels, long term low temperature bainite annealing and the Q-P process (quenching and partitioning). In the experimental program the intercritical annealing and the Q-P process were tested on two low alloyed steels with carbon content of about 0.2 %, chromium content between 0.09 and 0.79% and manganese content in the interval from 0.6 to 1.5 %. The influence of various cooling rates on the structure development and mechanical properties was examined for both types of treatment. Additionally the impact of different quenching temperatures in the Q-P process was also investigated. The influence of chromium on the morphology of the hardening phase was analysed metallographically. On the experimental specimens multiphase structures with various amounts of ferrite, bainite, retained austenite and MA constituent were achieved. The tensile strength after the Q-P process exceeded 830 MPa with ductility above 30%.
