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 engineers have developed the ability to manipulate structure and matter at the nanoscale for solid-state alloys ...

Body-centred cubic (bcc) metals exhibit a distinct plastic response arising from the motion and interaction of dislocations, line defects whose behaviour departs markedly from that in close-packed ...

Dislocations have a significant effect on mechanical, electronic, magnetic and optical properties of crystals. For a dislocation to migrate in bulk crystals, collective and simultaneous movement of ...

Mechanical structures are only as sound as the materials from which they are made. For decades researchers have studied materials from these structures to see why and how they fail. Before ...
