Manganese steels have many advantages, including low cost, corrosion resistance [7-18]. [...]they are suited to use in shipbuilding, and the land of the automobile industry. The characterization of the microstructures and the surface morphology of the alloy before and after heat treatment were studied by optical microscopy, scanning electron microscope, X-ray diffraction (XRD) and thus the hardness measurements indicate the evolution of the mechanical properties of our steel. 2.MATERIALS AND METHODS The alloy that will be the subject of the metallurgical study is manganese steel. [...]the observation of the structure by scanning electron microscope shows that the structure is heterogeneous, this observation is similar to the optical microstructure obtained in Fig. 4. Stitch parameters have been refined from the experimental positions of diffraction lines using the program PARAM [22, 23], we find that the crystal system changes from cubic to orthorhombic after heat treatment (Table 7). [...]as and as the treating temperature increases, the cell volume decreases, passes from 46.9 A°3 to 45A°3.
