    Influence of Hot Rolling Process on Microstructure and Properties of Low-strength IF Steel by Liu Gan, Ai Chengshen, Li Jiangwei, Kong Xianglei, Wang Yang, Huang Minghao

    Published 2025-02-01
    “…On the basis of the successful developed ferrite zone rolling process technology in a hot rolling plant production line, a comparative study was conducted to investigate the effects of two hot rolling processes, on the metallographic microstructure, precipitation phases, macroscopic texture and mechanical properties of low-strength IF steel. OM, TEM and XRD diffraction were used to compare and analyse the differences in metallographic microstructure, precipitation phases and macroscopic texture of IF steel in hot-rolled and cold-rolled annealed condition under the two rolling processes, and at the same time, the three-way tensile mechanical properties of IF steel were tested by the ZWICK tensile tester after cold-rolled annealing. …”
