Induction hardening is a widely used surface treatment technique that has extensively been
investigated. In contrast, induction tempering with short heating times≤ 1 s has not been …

Quenching is an important part of the production chain of steel components. The final
properties of the product are largely determined during this stage, and this renders …

We develop a macroscopic material model for visco-plastic material behavior accompanied
by phase transformations, which are important phenomena in steel production processes …

Modern surface hardening processes intend among other to induce compressive residual
stresses in the near-surface layers of the part. During subsequent tempering, these stresses …

Materials with residual stress can experience irreversible plastic strains as carbides
precipitate during the tempering process, thereby relaxing the residual stress. In previous …

Ein Prozessmodell zur Abbildung der induktiven Ein-und Zweifrequenzhärtung unter
Berücksichtigung prozessspezifischer Aspekte wurde entwickelt. Am Beispiel des …

We develop a multi-mechanism model for strainrate-and temperature-dependent
asymmetric plastic material behavior accompanied by phase transformations, which are …

In this work, we develop a thermodynamically consistent multi-scale model for the material
behavior of a low alloy steel taking elasto-viscoplasticity, heat conduction and phase …

This study uses a finite element method based simulation methodology for in-situ railhead
repair welding to investigate how welding process parameters impact the repaired rail …

In this contribution macroscopic modeling of phase transformations and mechanical
behavior of low alloy steels are developed and investigated. Such modeling is of importance …
