Screw dislocations play an important role in materials’ mechanical, electrical and optical properties. However, imaging the atomic displacements in screw dislocations remains challenging. Although ...

The relaxed state of a type of topological defect (screw dislocation) located in a dispersive (non-local) elastic solid is discussed from a viewpoint of gauge field theory. The starting point of this ...

THE superior mechanical properties of nodular cast iron, in comparison with other cast iron, are believed to be due to the graphite which is present in a spheroidal form. Small additions of various ...
