Room temperature deformation mechanisms of a Fe–Mn–Al–C steel

Journal of Materials Research and Technology, 2023
This study aims to investigate the deformation mechanisms of an austenite-based duplex Fe–Mn–Al–C steel at room-temperature through uniaxial tensile tests, strain rate sensitivity and stress relaxation analysis.

p-deformation

Differential Equations & Applications, 2022
Summary: In this article we introduce the so called \(p\)-deformed algebra \(\mathcal{V}\). The notion of \(p\)-deformation is connected to the well-known \(q\)-deformation by the simple relation \(p = \frac{q^2+q^{-2}}{2}\). Thus the \(p\)-deformed algebra \(\mathcal{V}\) will have representations in terms of \(q\)-difference operators.

Development of the Metal Rheology Model of High-temperature Deformation for Modeling by Finite Element Method [PDF]

, 2019
It is shown that when modeling the processes of forging and stamping, it is necessary to take into account not only the hardening of the material, but also softening, which occurs during hot processing.
