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 ...

Scientists have expanded on a longstanding model governing the mechanics behind slip banding, a process that produces strain marks in metals under compression, gaining a new understanding of the ...

An international team of researchers, led by University of Toronto Engineering Professor Yu Zou, is using electric fields to control the motion of material defects. This work has important ...

· 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 ...

For decades researchers have studied materials from structures to see why and how they fail. Before catastrophic failure, there are individual cracks or dislocations that form, which are signals that ...

(Nanowerk News) An international team of researchers, led by Professor Yu Zou (MSE), is using electric fields to control the motion of material defects. This work has important implications for ...

Materials scientists at the Max-Planck-Institut für Metallforschung, Stuttgart have achieved significant plastic deformation in strontium titanate (SrTiO3), an oxide ceramic material hitherto believed ...
