Grain refinement provides an effective way to improve the strength of low‐carbon steel without loss of room temperature ductility. The microstructure evolution of Cu–P–Cr–Ni–Mo weathering steel during multi‐pass deformation was investigated via hot compression simulation. The results indicated that...
