In refractory multi-principal element alloys (RMPEAs), the rapid atomic diffusion occurring near dislocations facilitates local segregation and chemical ordering, leading to the formation of unique ...

Schematic revealing strain-dependent mechanism transitions (shearing to Orowan looping) across different grains and the resulting evolution of dislocation types and configurations. As the aerospace ...

In situ straining tests in high purity α-Fe thin foils at low temperatures 1 have demonstrated that crystal line defects, called dislocations, have a jerky type of motion made of intermittent long ...
