Modeling Bainitic Transformations during Press Hardening. [PDF]
Materials (Basel), 2021 We revisit recent findings on experimental and modeling investigations of bainitic transformations under the influence of external stresses and pre-strain during the press hardening process. Experimentally, the transformation kinetics in 22MnB5 under various tensile stresses are studied both on the macroscopic and microstructural level. In the bainitic

Experimental and Numerical Process Design for Press Partitioning of the New Q&P Steel 37SiB6
Metals, 2023 Quenching and partitioning (Q&P) heat treatments of low-alloy steels with exceptional property combinations are particularly promising. In this study, we characterize for the first time a new low-alloy steel to be processed using Q&P heat treatments.

Press Hardening of High-Carbon Low-Density Steels. [PDF]
Materials (Basel)In this study, sheets of experimental high-carbon low-density steels (LDSs) with a thickness of 1.7 mm were processed in a combined tool designed for press-hardening. Press hardening, also known as hot stamping or hot press forming, is a manufacturing process used to create car body parts with exceptional mechanical properties and safety standards ...

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 ...

Fatigue Performance of Laser Welds in Heavy-Gage Press Hardening Steels
Metals, 2022 This work investigates and compares the fatigue performance of laser-welded joints of two press hardening steels: a standard 22MnB5 and a variant modified by a combination of niobium and molybdenum (NbMo) alloying.
