【Abstract】 Based on the explicit finite element simulation and experiment, the effect of plastic strain, shear strain and temperature and precipitation on structure of 0.05 C steel sheet produced by compact strip production (CSP) technology has been studied. The research results show that with heavy rolling deforming and deformation-induced precipitation the grain size of steel decreases to 6.5 μm in finished products from 170 μm in slab.更多还原
