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 ...

A research team co-led by materials scientists from City University of Hong Kong (CityU) has recently discovered a new mechanism to increase the strength and ductility of a high-entropy alloy, two ...

AT present the explanation of the origin and growth of crystals from solutions at low supersaturation or from melts which have been supercooled involves various aspects of the dislocation theory.

It has been found that the mechanical properties of small volumes significantly differ from those of bulk volumes for a wide variety of materials. Several methods are available for increasing the ...
