Multi-pass cold rolling and wire drawing process of gadolinium and its magnetocaloric effect

Journal of Materials Research and Technology, 2022
Owing to low ductility of magnetocaloric material (MCM)s, the plastic deformation process is quite challenging, and information available on the deformation process of MCMs is limited. In this study, the cold rolling and wire drawing processes of Gd wire
