Corrosion Mechanisms of High-Mn Twinning-Induced Plasticity (TWIP) Steels: A Critical Review

Twinning-induced plasticity (TWIP) steels have higher strength and ductility than conventional steels. Deformation mechanisms producing twins that prevent gliding stacking of dislocations cause a steel grades with the same strength. TWIP are considered to be within new generation advanced high-strength (AHSS). However, some aspects, such as corrosion resistance performance in service materials, need more research. Application automotive industry requires proper investigation behavior mechanisms, which would indicate optimum degree protection possible decrease costs. In general, Fe?Mn-based alloys can passivate oxidizing acid, neutral, basic solutions, however they cannot reducing acid or active chloride solutions. become potential material interest for applications due their effectiveness, impact resistance, negligible harm environment. The mechanical is subjected manufacturing processing steps, like forging casting, elemental composition, thermo-mechanical treatment. Corrosion caused by both intrinsic extrinsic factors has posed serious problem use. Passivity breakdown pitting, galvanic phase segregation widely described critical examined. Numerous studies been performed study passivation steel. Despite large number articles on corrosion, few comprehensive reports published this topic. current trend development thoroughly studied represented, showing key influencing processes, its consequences addition, suggestions future works gaps literature considered.
