A quantitative insight into strain hardening behavior of typical Hadfield steel under dynamic load

Journal of Materials Research and Technology, 2023
In this paper, the critical threshold associated to the activating of strain hardening capacity with respect to typical Hadfield steel Mn13Cr2 was explored quantitatively utilizing a Separated Hopkinson Press Bar (SHPB).

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 ...

Control-Oriented Characterization of Product Properties during Hot Hole-Flanging of X46Cr13 Sheet Material in a Progressive-Die

Metals, 2021
Robust and versatile production is enabled by a closed-loop control of product properties. This essentially relies on the characterization of the interaction between properties and available degrees of freedom to control the process.

On stress resultant plasticity and viscoplasticity for metal plates [PDF]

, 2008
In this work we derive elastoplastic and elastoviscoplastic finite element formulations for stress resultant bending analysis of thin metal plates. The principle of maximum plastic dissipation is used to obtain the ingredients of the small strain stress ...

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.

The Assembly and Merging History of Supermassive Black Holes in Hierarchical Models of Galaxy Formation [PDF]

, 2002
We assess models for the assembly of supermassive black holes (SMBHs) at the center of galaxies that trace their hierarchical build-up far up in the dark halo `merger tree'.
