Grain boundary strengthening
Videos
In materials science, grain-boundary strengthening is a method of strengthening materials by changing their average crystallite size. It is based on the observation that grain boundaries are insurmoun

Deformation mechanism
Videos
In geology and materials science, a deformation mechanism is a process occurring at a microscopic scale that is responsible for deformation: changes in a material's internal structure, shape and volum
Grain boundary strengthening
…to inverse Hall–Petch fundamentally depends on the activation energy of grain boundary sliding. This is because in direct Hall–Petch the dominant deformation mechanism is intragrain dislocation motion while in inverse Hall–Petch the dominant mechanism is grain boundary sliding. It was concluded that by plotting both…
