Abstract
A nanocrystalline CoCrNi alloy of ~50â¯nm grain size with the ultra-high ultimate tensile strength of ~2.2â¯GPa and fracture strain of ~9% was fabricated using high-pressure torsion. The presence of high density of nano-twins, stacking faults, dislocations, and nano-grains is attributed to the superior mechanical properties.
