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.

Effect of Cr on high-temperature oxidation resistance of Cr–Si–Mn alloyed press-hardened steel during press hardening

Journal of Materials Research and Technology
It is of great interest to overcome the problem of high-temperature oxidation of press-hardened steels (PHS) in press hardening with a cost-effective Cr alloying strategy.

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 ...

Laser Oscillating of Nickel Alloyed Welds on Press-Hardened Steel [PDF]

Chinese Journal of Mechanical Engineering, 2021
AbstractLaser oscillating welding was employed to fabricate Al-Si coated press-hardened steel (PHS) to improve the element homogeneity in the fusion zone. Laser oscillating welding was employed with various oscillation amplitudes (0 mm, 0.5 mm and 1.3 mm) in this present.

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.

Influence of the quenching temperature on the phase composition, structure, and wear resistance of 150XHM steel [PDF]

, 2013
The influence of the quenching temperature on the quantity of residual austenite, its stability, and its ease of deformational martensitic transformation in 150XHM steel is studied. In the addition, the hardening and abrasive-wear resistance of the steel

A multiscale perspective on the kinetics of solid state transformations with application to bainite formation

AIMS Materials Science, 2015
We give an excerpt of recent developments in the experimentally benchmarked modeling of bainite formation in the press hardening process. As the press hardening process poses a heavily multi-parameter dependent modeling challenge, we focus on three main ...
