CONFORM.AR Substitute traditional steels for plasticity steels induced by twinning -TWIP- in the automotive industry to mitigate climate change.
Description
It is proposed to develop a twinning induced plasticity (TWIP) steel with composition Fe-22Mn-0,6C-1,5Al, which combines high strength and ductility properties (maximum stress of 1200 MPa and elongation at fracture of 60%), produced at the Rosario Physics Institute (UNR-CONICET) for the automotive industry. It seeks to generate Technological Data for the socio-productive environment of Rosario and its region, incorporate laboratory capacities to carry out non-routine mechanical tests, characterization and technological properties (formability, weldability), as well as computational modeling for the forecast of fracture, and consolidate the research carried out on high mechanical performance steels that maintain high ductility. The substitution of traditional steels for these TWIP effect steels allows to reduce the necessary sections and, therefore, the weight of the vehicles. This development aims to replace structural parts of traditional steels with more resistant steels, contributing to the global effort to reduce the emission of CO gases.2 by reducing the weight of vehicles and mitigating climate change. In response to this objective and the regional socio-productive context, three aspects will be considered: scaling of production, generation of technological data incorporating the characterization of formability, weldability, and breakage; and the understanding at the microscopic and mesoscopic scale of the role of deformation mechanisms and their relationship with the specific microstructure of the Fe-22Mn-0,6C-1,5Al alloy. Going from a production of 5 kg to one of 100 kg will allow a precise control of the chemical composition and have a sufficient volume of material to make test tubes of sufficient dimensions and quantity to carry out tests that allow the gathering of reliable and transferable Technological Data. That will allow the adoption of TWIP steels by automotive and metal-mechanic companies in the region. The application of TWIP sheets to the forming of parts with complex shapes and/or their use in welded components, also leads to the generation of knowledge through phenomenological and physical analyzes of the mechanisms involved at the macroscopic, mesoscopic and microscopic scale.
