摘要：
The influence of continuous mill 2000 hot rolling parameters on the high strength dual-phase (DP) steel with experimental chemical composition structure evolution was investigated. In order to obtain dual-phase microstructure modern computer and physical simulation methods are used during development of hot rolling schedules. Computer simulation of structure and mechanical properties formation was realized with the help of Hot Strip Mill Model (HSMM), ThermoCalc and AusEvol+ programs. Physical simulation of metal thermomechanical treatment was made by Gleeble-3800 using "tension-compression" technique. Varying the thermomechanical treatment parameters the ferrite-martensitic (FM) dual-phase steels of DP780-DP1180 strength class are received.
