Preventing delayed cracks in SUS304 deep drawn cups using extreme blank holding forces aided by nanolubrication
Disappearance and reappearance of delayed cracks were observed in deep drawing process of SUS304 cylindrical cups under elevated blank holding forces (BHF) of 8~32 kN with nanolubricants containing 1~3 wt% SiO 2 concentrations at limiting draw ratio. The widest crack-free BHF range determined experi...
