WebAbstract. This article discusses the effect of alloying on the composition, structure, properties, and processing characteristics of ordered intermetallic compo WebIntermetallics are materials consisting of a combination of different metals, which results in an ordered crystallographic structure [7] that forms when the concentration of the alloys exceeds the solubility limit [12]. These materials are known to have crystal structure and properties that are different from their parent metals [3].
