Crystallization and interruption
WebA planar defect is a discontinuity of the perfect crystal structure across a plane. Interfacial defects are boundaries that have two dimensions and normally separate regions of the materials that have different crystal structures and/or crystallographic orientations. Interfacial defects exist at an angle between any two faces of a crystal or ...
