摘要：

The serrated flow behavior of a Fe-Mn-C twin-induced plasticity steel was investigated at room temperature. Tensile tests were performed at various strain rates under extensometer-measured strain control, as compared to conventional crosshead displacement-controlled tests. Different types of serrations were observed with type C ones identified for the first time. (C) 2012 Elsevier B.V. All rights reserved.
