Laboratory melting, casting and forging of manganese TWIP steel

Purpose: The article deals with the possibility of experimental melting, casting and forging of these kinds of steel in laboratory induction melting furnace Design/methodology/approach: The metallographic tests and Rastegaev compression test were made to describe microstructural properties and flow stress behaviour at different forging temperatures. Findings: Results of this test show the true stress - true plastic strain diagrams which can be used as a data input to the numerical simulation of forging for example in DEFORM 3D simulation software. Research limitations/implications: Microstructure analysis proved successful handling during all forging operations - no cracks and similar defects were observed in the microstructure. Practical implications: Transportation industry demands high strength steels with the possibility to absorb high energy in case of a sudden collision. In recent years, so-called TWIP steels are in the focus of research of materials with high strength suitable for car bodies. Originality/value: TFeMn TWIP is a high-strength steel concept with superior formability, which may be close to being produced industrially. High manganese TWIP steels are highly ductile, high strength Mn austenitic steels characterized by a high rate of work hardening resulting from the generation of deformation-nucleated twins.
