Abstract
High manganese austenitic stainless steels are being used to avoid nickel and its related issues. The aim of this thesis is to design, produce and investigate a series of high manganese austenitic stainless steel with carbon, chromium and aluminum addition.
A thermodynamic model was used for stacking fault energy calculations for alloy design. The produced alloys underwent cold deformation and heat treatments. The resulting microstructures were studied. Hardness and compression tests were used to investigate mechanical.
The results indicate that thermodynamic modeling of SFE is a valid approach. The produced alloys showed superior strength, ductility.
