Achieving ultra-high strength in Cr-bearing high-Mn austenitic steel via sub-minute annealing process and heterogeneous microstructure design
Source abstract
Abstract
In this study, a Cr-bearing high-manganese austenitic steel with a yield strength exceeding 1 GPa was developed. The production method involved cold rolling followed by sub-minute annealing, resulting in a complex microstructure comprising nano/ultrafine grains, deformation twins, nano precipitates, and regions of high dislocation density. This processing route significantly enhances the tensile properties of the steel, offering a promising method for manufacturing ultra-high-strength stable austenitic steels with suitable ductility.
