Hydrogen embrittlement characteristics of hot-stamped 22MnB5 steel

International Journal of Hydrogen Energy, 2021
Abstract Hydrogen embrittlement (HE) characteristics of 22MnB5 steel (U-bent specimen) manufactured using hot-stamping process at various temperatures were experimentally and numerically investigated. Steel resistance to HE was examined through delayed failure tests under static and cyclic loading during hydrogen charging.

Characterization of the Bendability of Press‐Hardened 22MnB5 Steel

Steel Research International, 2014
The bendability of press‐hardened 22MnB5 steel was used as evaluation criterion to assess the ability of a press‐hardened part to deform plastically in side impact crash conditions. The initiation sites of crack initiating shear bands during the bending operation of press‐hardened 22MnB5 steel were found to be formed by surface roughening.

On the ferrite and bainite transformation in isothermally deformed 22MnB5 steels

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2012
Abstract The effect of austenite deformation on ferrite transformation and bainite transformation is reviewed in this paper. In the ferrite zone on continuous cooling transformation (CCT) diagram of 22MnB5 steel, isothermal tensile tests were carried out in various deformation conditions on Gleeble 3800 thermo-mechanical machine, and microstructures ...
