A microstructure of 3-rd generation advanced high strength steel treated by Q&P (quenching and partitioning) process was obtained. Numerical simulation of hot rolling on continuous mill 2000 by means of HSMM software (Hot Strip Mill Model) was utilized. Developed by numerical simulation schedules were realized on physical simulator Gleeble-3800 using tension-compression technique. The maximum retained austenite volume fraction 12.22 % located on ferrite-martensite-bainite boundaries was observed. Received after physical simulation samples were tested, maximum measuring tensile elongation 24.7 % and tensile strength about 1270 MPa were received.
