Ecological and Economic Feasibility of Inductive Heating for Sustainable Press Hardening Processes
Journal of Sustainable Development of Energy, Water and Environment Systems, 2023 Press hardening is an established process for the production of high-strength lightweight structural automotive parts, like the B-pillar. While lightweight design is an important aspect of emission reduction during the use phase, emissions arising in ...

Tensile deformation behavior of TRIP-aided bainitic ferrite steel in the post-necking strain region
Science and Technology of Advanced Materials: Methods, 2021 Transformation induced plasticity (TRIP) steels present a remarkable balance of strength and ductility. However, their post-necking hardening behavior, which is required for press-forming and automobile crash simulation, is unreliable because of their ...
