... Abstract In some phase diagrams, the appearance of several reactions is the result of the presence of intermediate phases. These are phases whose chemical compositions are intermediate between two pure metals, and whose crystalline structures are different from those of the pure metals...

... in the determination of properties as well. In fact, a half-century ago it was not uncommon to hear from practitioners that metallic alloys failed by “crystallizing,” a statement that implicitly assumed that alloys in service were amorphous and lacked crystalline structure. (It is unfortunate that “failure...
