A REVIEW OF THE MECHANICAL-PROPERTIES OF B2 COMPOUNDS

The mechanical properties of B2 compounds are reviewed and their major features outlined by citing specific examples. B2 compounds exist in a wide range of alloy systems and thus exhibit many different types of mechanical behavior. Generally, the mechanical properties of B2 alloys depend strongly on the concentrations of constitutional defects; that is, on the constitutional vacancies and antisite atoms present, and hence on the composition. For disorderable compounds, the mechanical properties also depend strongly on the degree of order.
