WebIn this study, it was investigated how the characteristics of work hardening of the steel C-0.06, Mn-25, Al-3, Si-2, Ni-1, with TWIP effect influences their mechanical properties. This research used optical micrographs and scanning electron (SEM) for assessment of grain size and volume fraction of recrystallized grains. WebA specific 4-post assembly tool was designed to guarantee the best punched hole quality. Different punching speeds, from 0.2mm/s to 367mm/s were tested on different steel sheets (mild steel, AHSS including TWIP and 3 rd Gen steel) to emphasize or not the influence on final HER values.
