The role of slip transfer at grain boundaries in the propagation of microstructurally short fatigue cracks in Ni-based superalloys
M. Jiménez, W. Ludwig, D. Gonzalez +1
Crack initiation and propagation under high-cycle fatigue conditions have been investigated for a polycrystalline Ni-based superalloy by in-situ synchrotron assisted diffraction an…
Tensile deformation and fracture mechanisms of Cu/Nb nanolaminates studied by in situ TEM mechanical tests
Z. Liu, M. A. Monclús, L. W. Yang +3
The mechanisms of deformation and failure of Cu/Nb nanolaminates manufactured by accumulated roll bonding were analysed using in-situ TEM mechanical tests. Dog-bone small-scale ten…
An atomistic investigation of the interaction of dislocations with Guinier-Preston zones in Al-Cu alloys
G. Esteban-Manzanares, E. Martínez, J. Segurado +2
The interaction between edge dislocations and Guinier-Preston zones in an Al-Cu alloy was analyzed by means of atomistic simulations. The different thermodynamic functions that det…
Discrete dislocation dynamics simulations of dislocation- precipitate interaction in Al-Cu alloys
R. Santos-Güemes, G. Esteban-Manzanares, I. Papadimitriou +3
The mechanisms of dislocation/precipitate interaction were studied by means of discrete dislocation dynamics within a multiscale approach. Simulations were carried out using the di…
Influence of temperature on the strain rate sensitivity and deformation mechanisms of nanotwinned Cu
L. W. Yang, C. Y. Wang, M. A. Monclús +3
The mechanical behavior of nanotwinned Cu was studied through indentation creep and constant strain rate indentation tests from 25 C to 200 C. The results showed an…
Crystal plasticity simulation of the effect of grain size on the fatigue behavior of polycrystalline Inconel 718
A. Cruzado, S. Lucarini, J. LLorca +1
A microstructure-based model that accounts for the effect of grain size has been developed to study the effect of grain size on the fatigue life of Inconel 718 alloys. The fatigue…
