Positive strain rate dependence: optimizing TRIP effect for high-speed deformation in lean duplex stainless steel

We developed a unique lean duplex stainless steel with a highly unstable austenite phase, exhibiting positive strain rate dependence in tensile properties. Specifically, increased strain rates enhanced the strength-ductility synergy. Adiabatic heating was actively utilized to stabilize austenite, ex...
