HIGH STRENGTH DUAL-PHASE STEEL STRUCTURE EVOLUTION DURING HOT ROLLING

摘要

The influence of continuous mill 2000 hot rolling parameters on the high strength dualphase (DP) steel structure evolution was investigated. Computer simulation of structure and mechanical properties formation was realized with the help of Hot Strip Mill Model (HSMM), ThermoCalc, AusEvol+ programs. Physical simulation of metal thermomechanical treatment was made by Gleeble-3800. Varying the thermomechanical treatment parameters the ferritemartensitic (FM) dual-phase steels are received.
