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.

A dislocation running through the trunk of a nanowire offers a new twist to the growth of chiral branched nanostructures, producing beautiful tree-like structures in the process. The central trunks of ...

The diagram shows the effect of 'sliding' an Edge (a), Screw (b), or Mixed (c) dislocation completely across a slip plane in the crystal. Each dislocation has the same effect as it moves completely ...

Materials scientists have recently discovered a new mechanism to increase the strength and ductility of a high-entropy alloy, two properties which normally vary inversely with each other. The findings ...

In this work, we propose dislocation mechanisms for the formation of {10 $\bar 1$ 1}—{10 $\bar 1$ 2} double twin structures in hexagonal close packed (HCP) crystals through the nucleation of secondary ...

A new study published in Engineering delves into the material removal mechanisms in ultra-high-speed machining (UHSM), a key technology in advanced manufacturing. High-performance engineering ...

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 ...
