Partial dislocation slip induced plasticity

Both twinning and transformation can produce a macroscopic strain and cause a significant plastic deformation, which are known as twinning-induced plasticity (TWIP) and transformation-induced plasticity (TRIP), enhancing the plastic deformability of structural materials dramatically. As far as the authors believe, the underlying origin behind these kinds of plastic deformation should not be the twinning and transformation themselves. By deciphering microstructural origins of the two effects in a kind of interstitial high entropy alloy (iHEA), the slip of partial dislocations causing TWIP and TRIP is analogous to the full dislocation slip governing ductility of materials, determines the plastic deformation.
