Characterization of dislocation motion in the alloy using discrete dislocation dynamics (DDD) simulations. Video showing the effect of lattice strain field on the dynamic evolution of dislocations ...

· Dislocation motion in crystals can occur when a shear stress act across the slip plane. This is illustrated for an edge dislocation. · The atomic structure is only adjusted in the region of the ...

The energy of a dislocation depends on its position in its slip plane. The diagram represents a slip plane with a position dependent potential having a period, a, determined by the location of rows of ...

A new study investigates cyclic deformation in a 3D printed high entropy alloy, a step toward predictable fatigue life for metal AM.
