Effects of nanostructural hierarchy on the hardness and thermal stability of an austenitic stainless steel

An austenitic stainless steel was processed by high-pressure torsion, and formed a hierarchical nanostructure with ultrafine grains, ultrafine-precipitates, nano-twins and high densities of dislocations. As a result, the hierarchical nanostructure contributes collectively to the double hardness valu...
