The compression tests were performed at different temperatures from 25 to1000°C to study the mechanical behavior of advanced austenitic steel with 21% manganese plus bearing Ti. The results indicated that the plastic deformation is controlled by deformation-induced martensite and mechanical twinning from 25 to 100°C. However, at temperatures 200 to 1000°C the deformation twinning was merely observed. The occurrence of mechanical twinning at such high temperatures is a first-time observation in high manganese austenitic steels. Such mechanical twins led to grain refinement via grain partitioning.}, keywords = {Metals and alloys,Phase transformation,Microstructure}, title_fa = {Effect of Deformation Temperature on the Mechanical Behavior of a New TRIP/TWIP Steel Containing 21% Manganese}, abstract_fa = {}, keywords_fa = {}, url = {https://journal.issiran.com/article_6503.html}, eprint = {} }
