Abstract Scope |
Grain boundary is one of the most important crystalline defects in crystalline metals and alloys. The structure and behavior of grain boundary often determine the mechanical as well as many physical properties of materials. Grain boundary structures can be dependent on temperature, stress and other factors, thus the grain boundary structures in real materials are usually more complicate than ideal grain boundaries proposed by theory. During the plastic deformation of metals and alloys, grain boundaries become obstacles for dislocation slips and thus introduce a strengthening mechanism to the materials. In this work, we have employed transmission electron microscopy to resolve grain boundary structures in metallic materials and the interaction between dislocation slips and grain boundaries during plastic deformation. |
