Effect of sample thickness on the tensile behaviors of Fe-30Mn-3Si-3Al twinning-induced plasticity steel
Unexpectedly, the total flow stress curves of Fe–30Mn–3Si–3Al twinning-induced plasticity steel before tensile fracture are almost overlapped with the decreasing sample thickness, which is significantly different from reported results of traditional metallic materials. The reason is the activated mechanical twins inhibit the dislocation movement and refine the crystalline structure.
