What is an interface? What are different types of interfaces

What is an interface? What are different types of interfaces Where two homogeneous bulk phases meet there is a region of finite thickness where the  properties change, often markedly, as we move from one bulk phase to the other. Such  regions are known as surfaces or interfaces. Although we may commonly think of a surface  as being of negligible thickness, in fact, when we are discussing phenomena at a molecular  level the thickness of the interfacial region is significant and definitely non-zero. Because there are three types of bulk phase, it is possible to classify interfaces based on the  nature of the bulk phases that lie on either side of the interface. Thus, there are five types of  interface:   Quiz1 complete solution is here:  https://www.iitdocs.com/2026/05/quiz-solution-mse-639-interfaces-and.html

What is the angular range  for low angle boundary? 2+1  (c) How does a coherent twin boundary differ from an incoherent twin boundary? 2  (d) For FCC Ni (lattice parameter = 0.361 nm) tilt boundary (tilt angle = 5 degrees), estimate the  spacing between dislocations? 3 Solutions:  Answer  (a) Three types: Coherent, Semicoherent and Incoherent  (b) Simple schematic diagram of low angle grain boundary. A low-angle tilt boundary is an  array of parallel edge dislocations
