Induced Surface Austenitic-Martensitic Transition by Mechanical Deformation in Mn Steel.Effect of Surface Properties

摘要：

For a lot of applications in the mechanical industry, both attractive and mechanical properties of materials and wear resistance are required. Usually such a combination is achieved only by performing surface treatments.The aim of this investigation is the consolidation of 12％ Mn steel surface by treatment of impacts.We show by optical and scanning electron microscopy, X ray diffraction, X ray spectrometry analysis and also by the realization of micro hardness, the effect of this kind of treatment on the mechanical and structural stability of the surface zone. Among of many obtained results, we distinguish the clear surface consolidation induced by a modification of surface zone crystalline structure. The mechanical deformation causes the transformation from an austenitic structure to the martensitic structure.
