| Abstract | Dynamic strain aging region for austenitic stainless steel 316 wasinvestigated from room temperature to 650°C at constant strain rates of 1x10-2,1x10-3 and 1x10-4 sec-1. Characteristicsindicators of serrated plastic flow were observed in the temperature range of 400°Cto 600°C at these strain rates. Strain rate sensitivity of the material isfound to be negative in this region. Study of fracture surface of tensile testspecimen by scanning electron microscope revealed that ductility in this regionis decreased. The limiting drawing ratio of sheet metal is the indicator offormability in deep drawing. LDR of the sheet metal was estimated by performingthe deep drawing of different diameter blanks in finite element simulationsoftware LS-DYNA in DSA temperature region. It was observed that in DSA regionformability of sheet metal decreased. These simulations are validated andcompared with experimental results. |
