Discrete dislocation and crystal plasticity analyses of load shedding in polycrystalline titanium alloys [PDF]
The focus of this paper is the mechanistic basis of the load shedding phenomenon that occurs under the dwell fatigue loading scenario. A systematic study was carried out using a discrete dislocation plasticity (DDP) model to investigate the effect of ...

Critical stress statistics and a fold catastrophe in intermittent crystal plasticity [PDF]
The statistics and origin of the first discrete plastic event in a one dislocation dynamics simulation are studied. This is done via a linear stability analysis of the evolving dislocation configuration up to the onset of irreversible plasticity. It is found, via a fold catastrophe, the dislocation configuration prior to loading directly determines the

This study investigates the bond quality of co‐extruded aluminum–titanium hybrid profiles, focusing on the lateral angular co‐extrusion (LACE) process. It examines how heat treatments (HT) affect intermetallic phase formation, bond strength, and material properties.

Effect of a weak magnetic field on ductile-brittle transition in micro-cutting of single-crystal calcium fluoride [PDF]
Magneto-plasticity occurs when a weak magnetic field alters material plasticity and offers a viable solution to enhance ductile-mode cutting of brittle materials. This study demonstrates the susceptibility of non-magnetic single-crystal calcium fluoride (CaF2) to the magneto-plastic effect.

Pantolactone as a plastic crystal.
D-Pantolactone crystals showed anomalous thermal behavior, that is, two endothermic peaks (62.0 and 91.6°C) were observed in the differential scanning calorimetry curves. The entropy change of the first transition was calculated as 44.4 JK-1 mol-1 and that of the second transition was 9.20 JK-1 mol-1.

Mesoscale model of dislocation motion and crystal plasticity
A consistent, small scale description of plastic motion in a crystalline solid is presented based on a phase field description. By allowing for independent mass motion given by the phase field, and lattice distortion, the solid can remain in mechanical ...
