Serrated Flow in 316LN Austenitic Stainless Steel

Serrated flow behavior of the 316LN austenitic stainless steel was investigated through tensile tests at initial strain rates of 2×10 -5 to 10 -4 s -1 at temperatures ranging from room temperature to 1048 K. Serrated flow occurred at room temperature and 6981048K at the strain rate of 2×10 -4 s -1 , as well as at temperatures of 623673 K at the strain rate of 2×10 -5 s -1 . Type A, A+B, C and E serrations appeared. The activation energy for the...
