Grain Boundary Property Determination through Measurement of Triple Junction Geometry and Crystallography

摘要: Microstructure controls the properties of most useful materials. Thus an ability to control microstructure through processing materials is a key optimization performance. Most are polycrystalline and their grain structure very important aspect microstructure. Thanks complexity there great variety boundary types even in relatively isotropic such as cubic metals. Simply describing crystallography requires five (macroscopic) parameters (e.g. disorientation inclination). Evidently, acquiring knowledge variation energy mobility function type would be value predicting optimizing processing. This paper outlines methods being employed extract from geometry triple junctions between boundaries.
