Project
CONFORM.AR Substitute traditional steels for plasticity steels induced by twinning -TWIP- in the automotive industry to mitigate climate change.
Description
This project proposes the development of a twinned plasticity-induced (TWIP) steel with the composition Fe-22Mn-0,6C-1,5Al, combining high strength and ductility (1200 MPa tensile strength and 60% elongation at fracture), produced at the Rosario Physics Institute (UNR-CONICET) for the automotive industry. The aim is to generate technological data for the socio-productive environment of Rosario and its surrounding region, incorporate laboratory capabilities for non-routine mechanical testing, characterization, and analysis of technological properties (formability, weldability), as well as computational modeling for fracture prediction, and consolidate research on high-performance steels that maintain high ductility. Replacing traditional steels with these TWIP steels allows for a reduction in the required cross-sections and, consequently, the weight of vehicles. This development aims to replace traditional steels in structural components with stronger steels, contributing to the global effort to reduce CO2 emissions by decreasing vehicle weight and mitigating climate change. Addressing this objective and the regional socio-productive context, three aspects will be considered: scaling up production; generating technological data incorporating characterization of formability, weldability, and fracture; and understanding, at the microscopic and mesoscopic scales, the role of deformation mechanisms and their relationship to the specific microstructure of the Fe-22Mn-0,6C-1,5Al alloy. Increasing production from 5 kg to 100 kg will allow for precise control of the chemical composition and provide a sufficient volume of material to prepare test specimens of adequate dimensions and quantity for conducting tests that will yield reliable and transferable technological data. This will enable the adoption of TWIP steels by automotive and metalworking companies in the region. The application of TWIP sheets to the forming of parts of complex shapes and/or their use in welded components also leads to the generation of knowledge through phenomenological and physical analysis of the intervening mechanisms at the macroscopic, mesoscopic and microscopic scale.
