Different phase boundary - Different phase boundary

Japanese: 異相界面 - いそうかいめん
Different phase boundary - Different phase boundary

…Solid materials such as metals and ceramics are usually aggregates of many crystal grains. When adjacent crystal grains are of the same phase, the interface between them is called a grain boundary (also called a grain boundary or crystal boundary), and when they are of different phases, it is called a different phase interface or different phase boundary. The structure and properties of a different phase interface are similar to those of a grain boundary in many ways. …

*Some of the terminology used to refer to "interphase interfaces" is listed below.
