This allowed the selection of two materials with different crystal structures yet with sufficient chemical flexibility to grow in a completely ordered manner throughout the interface between them. (sciencedaily.com)
«These two states have the exact same composition but very different crystal structures,» he said. (sciencedaily.com)
In metal alloys, the shape memory effect is based on the phenomenon that they can exist in two different crystal structures as a function of a specific temperature. (sciencedaily.com)
