Shearing of γ'particles in Co-base and Co-Ni-base superalloys

L Feng, D Lv, RK Rhein, JG Goiri, MS Titus… - Acta Materialia, 2018 - Elsevier
Shearing mechanisms of the primary strengthening phase in cobalt-base and cobalt-nickel-
base superalloys, γ′(L1 2), are investigated at the elementary defect level by using a …

A study of dislocation junctions in FCC metals by an orientation dependent line tension model

L Dupuy, MC Fivel - Acta Materialia, 2002 - Elsevier
The formation and strength of dislocation junctions in FCC crystals have been calculated
using an orientation-dependent line tension model. The structure of the different types of …

Micromechanical model of the high temperature cyclic behavior of 9–12% Cr martensitic steels

B Fournier, M Sauzay, A Pineau - International Journal of Plasticity, 2011 - Elsevier
9–12% Cr quenched and tempered martensitic steels are known to soften under cyclic
loadings at high temperature. The present article proposes a model based on physical …

Surface relief evolution and fatigue crack initiation in René 41 superalloy cycled at room temperature

T Babinský, I Kuběna, I Šulák, T Kruml, J Tobiáš… - Materials Science and …, 2021 - Elsevier
Surface relief evolution and fatigue crack initiation of René 41 superalloy was studied. The
material was tested in two thermodynamical states: solutionised and aged. Cylindrical …

Elastic energy of a straight dislocation and contribution from core tractions

E Clouet - Philosophical Magazine, 2009 - Taylor & Francis
We derive an expression of the core traction contribution to the dislocation elastic energy
within linear anisotropic elasticity theory using the sextic formalism. With this contribution …

Nanoscale dislocation shear loops at static equilibrium and finite temperature

Atomistic simulations are used to determine the resolved shear stress necessary for
equilibrium and the resulting geometry of nanoscale dislocation shear loops in Al …

Microstructural characterization of creep anisotropy at 673 K in the M5® alloy

M Rautenberg, X Feaugas, D Poquillon, JM Cloué - Acta materialia, 2012 - Elsevier
Zirconium alloy tubing is used in pressurized water nuclear reactors in order to prevent
fissile material from leaking into the coolant. It can be the first safety wall of nuclear fuel, and …

Pinning of dislocations in disordered alloys: effects of dislocation orientation

M Zaiser, R Wu - Materials Theory, 2022 - Springer
The current interest in compositionally complex alloys including so called high entropy
alloys has caused renewed interest in the general problem of solute hardening. It has been …

Modelling of the internal stress in dislocation cell structures

EM Viatkina, WAM Brekelmans, MGD Geers - European Journal of …, 2007 - Elsevier
The nonuniform distribution of dislocations in metals gives rise to material anisotropy and
internal stresses that determine the mechanical response. This paper proposes a …
