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 ...
