Unprecedented strength in pure iron via high-pressure induced nanotwinned martensite

Unprecedented strength in pure iron via high-pressure induced nanotwinned martensite

Martensitic transformation can easily induce a maximum hardness value of 800–900 HV (Vickers hardness) for steels with carbon contents of 0.6 wt.% and above. However, the occurrence of martensitic transformation in pure iron requires exceptionally high cooling rates (105–106°C/s), and the maximum ac...
