Preventing delayed cracks in SUS304 deep drawn cups using extreme blank holding forces aided by nanolubrication / Muhammad Shafiq Ibrahim
This study was to investigate the formation and reformation of delayed cracks of SUS304 cylindrical drawn cups under elevated blank holding force (BHF) from 8~32 kN with 1~3 wt% SiO2 nanolubricants concentrations. The widest crack-free BHF range i.e. from 29 ~ 31 kN was determined for 2 wt% of SiO2...
