... to obtain an ultra-fine-grained structure (UFG). Upon achieving the grain size of 200 nm, the formability of the alloy at room temperature and at a high strain rate was investigated both experimentally and numerically. Micro deep drawing experiments were performed at different deep drawing ratios (1.66...

..., and also improves the quality of the component. As the varieties of TWB applications are increasing, the effects of the difference in material properties, weld, and its orientation on blank formability have become important both in deep drawing and stretch forming. In this work, high strength low alloy...
