摘要：
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 value of the austenitic stainless steel (514 +/- 44 HV) in comparison to the coarse-grained counterpart (217 +/- 11 HV). Both the nanostructural hierarchy and high hardness can be maintained at the temperatures up to similar to 600 degrees C. Annealing treatment at temperatures from 400 to 600 degrees C may induce recovery to the hierarchical nanostructure, resulting in a reduced microstructural heterogeneity and increased hardness for the high-pressure torsion processed steel.
