how to improve toughness in wpc

it's clearly a crazy and chaotic world out there, so it's no wonder that mental toughness (or grit, or whatever you want to call this sort of resilience) is having a bit of a moment. posts by my colleagues and me on signs of mental toughness, habits of mental toughness, even destroyers of mental toughness all .

wpc treatment improves surface hardness through the effects of work hardening, improving the wear resistance of the punch. because the hardness of a wpc-treated punch gradually increases moving from the inside of the punch toward the surface (fig.4) there is no loss of toughness in the punch base material.
