THE TWIP ALLOYs RESISTANCE IN SOME CORROSION REAGENTS
Original language description
he work deals with corrosion resistance of two high Mn alloys. After cast of the Fe22.3Mn0.5C alloy heat treated at 1200°C/4h/water and forging with total deformation of 25 % were carried out. This represents the TWIP 1 alloy. The TWIP 2 alloy is the TWIP 1 re-heated at 1150°C/3h/air. Final bars corresponded to 12 mm in diameter. Further the Fe23.1Mn0.73C alloy was laboratory rolled with the final strip thickness of 3 mm representing the TWIP 3 alloy. Exposition of all variants in the 3.5 % water NaCl solution showed corrosion on the boundaries of the twins first of all. The TWIP 3 demonstrated higher corrosion resistance. The worst corrosion attack showed the TWIP 2, where the corrosion traces reached 0.12 mm under surface. After the TWIP 3 alloy exposition in corrosion solution with bubbled hydrogen sulphide (the HIC test), no hydrogen cracks were revealed. The results were confronted with austenite grain sizes, formed twins and mechanical properties.
