TL;DR: The weight issue is therefore high on the agenda of BIW design, as it is directly related to environmental concerns, i.e. emissions of CO2, and the economics of the gas mileage.

TL;DR: In this paper, a high Mn TWIP (TWinning Induced Plasticity) steel and an Al-added TWIP steel (0.6C-18Mn-1.2Al steel) were fabricated, and their microstructures, tensile properties, and cup formability were analyzed to investigate effects of Al addition on deformation mechanisms in tensile and cup forming tests.

TL;DR: In this paper, a CALPHAD type thermodynamic description for the Fe-Mn-Al-C quaternary system has been constructed by combining a newly assessed Mn-Al−C ternary description and a partly modified Fe-Al•C description to an existing thermodynamic database for steels.

TL;DR: In this paper, an innovative pathway was developed to obtain liquid metal embrittlement-free welds which is able to extend the weldable current range of the steels. But this pathway is limited by the high electrical resistivity of twinning induced plasticity steels, which makes their resistance spot welding difficult and limits their weldability.

TL;DR: In this article, the effects of carbon content on cracking phenomenon in light-weight steel plates were investigated, and three steels were fabricated by varying carbon content, and their microstructures and tensile properties were investigated.
