Dislocation Cross-Slip in Face-Centered Cubic Solid Solution Alloys
The mechanical strength of metals depends on their resistance against various microscopic
deformation processes. In ductile metals, the most important process is shearing of the crystal
lattice by dislocations. One of the fundamental aspects of dislocation ...
EPFL2018Evolution of grain boundary network topology in 316L austenitic stainless steel during powder hot isostatic pressing
The grain boundary network evolution of 316L austenitic steel powder during its densification by hot isostatic pressing (HIPing) was investigated. While the as-received powder contained a network of random high angle grain boundaries, the fully consolidate ...
2017Ultra low cycle fatigue of welded steel joints under multiaxial loading
Albano António De Abreu E Presa De Castro E Sousa
Extreme loading scenarios such as earthquakes, exceptional wind gusts or tides are characterized by very high amplitude and multidirectional cyclic loads applied to a structure. Ultra Low Cycle Fatigue (ULCF) arises in such cases and can be summarily defin ...
EPFL2017Atomistic mechanisms of hydrogen embrittlement
The detrimental effects of the H on the mechanical properties of the metals are known for more than a century. One of the most important degradation mechanisms is H embrittlement (HE). In this thesis, we examined a few famous proposed mechanisms in the fie ...
EPFL2017An in-situ synchrotron study on microplastic flow of electrodeposited nanocrystalline nickel
Helena Van Swygenhoven, Steven Van Petegem
Deformation in nanocrystalline (NC) materials is strongly influenced by the presence of a large fraction of grain boundaries. We present a comparative study on the role of intragranular root-mean-square strain and crystal-lographic texture on recovery proc ...
Elsevier Science Sa2017The microstructure, mechanical properties and corrosion resistance of 316 L stainless steel fabricated using laser engineered net shaping
The mechanical properties and corrosion resistance of 316 L stainless steel fabricated using the Laser Engineered Net Shaping (LENS) technique have been studied. The crack-free, full density samples made using SS316L alloy powder and the LENS technique are ...
Elsevier Science Sa2016Comment on "Origin of low-temperature shoulder internal friction peak of Snoek-Koster peak in a medium carbon high alloyed steel" by Lu et al. [Solid State Communications 195 (2014) 31]
We want to discuss the interpretation of low-temperature shoulder internal friction peak of Snoek-Koster peak (LTS-SK). Lu et al. (2015) [1] attributed it to the interaction between the carbon atoms and twin boundaries in martensite. Nevertheless, the decr ...
Pergamon-Elsevier Science Ltd2016Microstructural characterizations of 14Cr ODS ferritic steels subjected to hot torsion
Oxide dispersion strengthened (ODS) steels are very promising materials for nuclear applications. In thispaper, the hot working behavior of ODS ferritic steels, consolidated by hot extrusion, is studied through torsion tests. Three ODS steels are produced ...
Elsevier2015Factors affecting the strength of P{011}〈566〉-texture after annealing of a cold-rolled Al–Mn–Fe–Si alloy
Elongated coarse P{011}-oriented grains are frequently observed after annealing of cold-rolled Al–Mn alloys with a highly supersaturated solid solution level. In this study, important factors affecting the strength of the P-texture component after ann ...
Springer2015Microstructural stability of ODS steels in cyclic loading
The remarkable microstructural stability of high chromium steels prepared by powder metallurgy and strengthened by dispersion of nanometric yttrium oxides in cyclic loading at high temperatures is reported. Contrary to the continuous cyclic softening and p ...
