Crystal interfaces and microstructure
WebMicrostructure. In many deformed or processed materials, the 3D orientation of the crystal lattices in the different grains is not random. The nature and degree of any alignment of these lattice orientations is known in materials science as “texture” (or in the geological sciences as “crystallographic preferred orientation”). WebThe precise control of the crystal structure, composition, and microstructure are desired for a high performance reliable component. The chemical processing technology has been …
