Serrated flow behavior in AL6XN austenitic stainless steel

Serrated flow behavior of the AL6XN austenitic stainless steel has been investigated at different temperatures and strain rates. The results show the serrated flow, peak/plateau in flow stress and negative strain rate sensitivity appearing in tensile deformation of the AL6XN steel at 773–973 K and 3.3 × 10−5–3.3 × 10−3 s−1 (excluding 873 K, 3.3 × 10−5 s−1), suggesting the occurrence of dynamic strain aging (DSA). The activation energy for type-A...
