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 ...

· 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 ...

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 ...
