Difference Between Hot rolling and cold rolling

Cold rolling is a process which passes metal through rollers at temperatures below its recrystallization temperatures. This increases the yield strength and hardness of the metal. This is done by introducing defects into the crystal structure of the metal creating a hardened microstructure which prevents further slip.

Cold Forming - ASSAB Malaysia

Press Forming is basically a cold bending operation used to shape, flange or make shallow impressions in parts previously blanked out or sheared from sheet. The most critical failure mechanisms for press forming of softer work materials

Effect of cold rolling on microstructure and texture evolution in

2021年12月25日 With increasing cold rolling reduction, the sizes of the recrystallized grain were slightly increased. When the cold rolling reduction was no more than 83.3%, the recrystallization textures were nearly random, see Fig. 7 (b) and (d). However, when the cold rolling reduction was up to 96.7%, a medium Cube texture and {001}texture were formed.
