Abstract

It has been revealed that the grain size effect has a great effect on the formability of metal foils during quasi-static forming processes. However, there is little research on how size effects influence the formability of metal foils during the high-speed forming process, e.g., electromagnetically-assisted forming. To characterize the grain size effect in electromagnetically assisted micro-bulging, a miniaturized Nakazima test was conducted using a specially designed device. Pure titanium foils of thickness 103 μm and different grain sizes were utilized in the experiment. In addition, SEM and TEM methods were used to clarify how grain size influences the fracture surface and microstructure in electromagnetic forming.
