Dislocation dynamics prediction of the strength of Al-Cu alloys containing shearable precipitates
R. Santos-Güemes, L. Capolungo, J. Segurado +1
The critical resolved shear stress of an Al 4 wt. \% Cu alloy containing a homogeneous distribution of precipitates was determined by means of dislocation dynamics simulation…
Nanomechanical characterization of the fracture toughness of Al/SiC nanolaminates
L. W. Yang, C. R. Mayer, N. Chawla +2
The fracture toughness of Al/SiC nanolaminates with different layer thicknesses (in the range 10 to 100 nm) was measured by means of micropillar splitting and bending of a notched…
Prediction of the Al-rich part of the Al-Cu phase diagram using cluster expansion and statistical mechanics
S. Liu, E. Martínez, J. LLorca
The thermodynamic properties of α-Al and other phases (GP zones, θ'', θ' and θ) in the Al-rich part of the Al-Cu system have been obtained by means of the cluster expansion formali…
A criterion for slip transfer at grain boundaries in Al
R. Alizadeh, M. Peña-Ortega, T. R. Bieler +1
