Unit cell volume of intermetallic compounds calculated using volume size factors

Abstract: Unit cell volumes of intermetallic compounds have been calculated using reported volume size factors. An equation to calculate unit cell volume for intermetallics of any crystalline structure was derived from previously reported expressions for L12 and B2 compounds. Average error for 122 analyzed compounds was 3.16%. Errors ranged from 0.00 to 14.01%. Factors that could influence the error value, such as order, structure type, solid solubility, and type of elements forming the compound were evaluated. A combination of solid solubility and type of elements forming the compounds seem to be the most relevant factors influencing the error value. [Copyright &y& Elsevier]
