Overdriven dislocation-precipitate interactions at elevated temperatures in aluminum
Amirreza Keyhani
The two-dimensional dislocation dynamics approach has been recently used for analyzing plastic deformation in metals and alloys at elevated temperatures. The two-dimensional approa…
Quantification of Dislocation-Precipitate Interactions
Amirreza Keyhani, Reza Roumina
The present research is the first attempt to systematically quantify the dislocation-precipitate interaction in terms of applied shear stress, precipitate resistance, and the requi…
Computational analysis of short-range interactions between an edge dislocation and an array of equally-spaced identical shearable or non-shearable precipitates
Amirreza Keyhani
The interaction between dislocations and precipitates plays an important role in the mechanical behavior of alloys. To provide more insight into the physics of this interaction, th…
Multi-scale Modeling of Plasticity Nearby Precipitates in Nanostructured Materials
Amirreza Keyhani
Precipitation strengthening is one of the most effective methods to design alloys with the desired combination of strength and ductility. The main mechanism of strengthening is gen…
