As an ideal candidate material for automobiles, twinning-induced plasticity (TWIP) steels possess excellent formability, high strength and high energy absorption ability during collision. This is attributed to its deformation mechanism of mechanical

In oil and gas and other industries, valve bodies are often manufactured using a 2.25Cr-1Mo steel which, if welded, requires post-weld heat treatment (PWHT) in order to restore toughness. The safe operation and long-term integrity of such welds is cr

The superior features of high manganese TWIP steels under deformation are believed to be originated from the induced twinning boundaries acting as barriers, hence impeding the activity of dislocation slips. We investigate the effect of different defo
