Abstract: Abstract The deformation behavior of Chromium (Cr) was investigated with the goal to understand and quantify the thermally-activated dislocation plasticity and the transition to the temperature-/rate-independent regime in body-centered cubic ( bcc ) metals. High-temperature… read more here.

DOI: 10.1016/j.jmps.2019.07.019
Abstract: Abstract Persson’s theory allows for a fast and effective estimate of contact area and contact stress distributions when a flat and a self-affine rough surface are pressed into contact. For elastic bodies, the results of… read more here.

DOI: 10.1016/j.jmps.2021.104581
Abstract: Abstract There is clear evidence in the literature that iron segregates to the interface of second phase particles (SPPs) in unirradiated Zr-Nb alloys, and that it does not do so in the presence of radiation… read more here.

DOI: 10.1080/21663831.2020.1741469
Abstract: ABSTRACT The mechanical properties of high-entropy alloys (HEAs) are still not deeply understood. Detailed knowledge of the strengthening mechanism, especially, the atomistic origin of solid solution hardening and its interplay with dislocation plasticity is needed.… read more here.
