High manganese steel is a commonly used engineering material,whose microstructure and properties are closely related to thermal deformation conditions.In the continuous casting solidification process of high manganese steel,the columnar crystals are developed,coarse and the solute microsegregation is serious,and there is a significant crack tendency and anisotropy.In this study,the stress and strain of high manganese steel and the relationship between the stress and strain and metallographic structure were discussed by thermal simulation test and metallographic observation under different compression rates and different temperatures,and the most suitable thermal deformation rate and temperature were found to provide the best thermal deformation parameters for ensuring the smooth completion of the continuous casting billet production of high manganese steel.For high manganese steel materials,under different thermal deformation conditions,the grain size of high manganese steel can be significantly improved,so that its structure and properties are also very different,the larger the grain size of the sample,the smaller the stress required under the same strain,that is,the easier the deformation during compression,when the grain size of the sample is smaller,the greater the stress required under the same strain,that is,the more difficult the deformation during compression.
