Bending Behavior of Zinc‐Coated Hot Stamping Steels

steel research international, Volume 92, Issue 10, October 2021., 2021
The bending behavior of zinc‐coated martensitic steels produced via two different cooling routes, namely, with and without precooling, is investigated. Precooling leads to the formation of individual ferrite grains within the martensitic matrix in the near‐surface regions.

Numerical modeling of the 22MnB5 formability at high temperature

Procedia Manufacturing, 2019
Abstract It has been recognized in automotive sector that the use of hot stamped parts for the automobile body-in-white allows significant weight saving and reduction of CO2 emissions. The weight reduction is accompanied by high stiffness and increased crashworthiness, which improve the passengers’ safety and allow the development of more complex ...

Characterization of Mechanical Properties, Macroscopic Deformation Behavior, and Microstructure of Functionally Graded 22MnB5 Steel

steel research international, Volume 92, Issue 7, July 2021., 2021
The focus of this study is on the characterization of the local plastic deformation and failure of functionally graded 22MnB5 steel after hot stamping using an in situ approach for analysis of properties. The experimental results reveal that the distribution of plastic strain of the graded sample is depending on the mixture of its constituting ...
