Pilling–Bedworth Ratio for Homogeneous Alloys: A Physically Sound Practical Generalization

Oxides containing only one metallic component as well as mixed oxides with several cations may form during oxidation of multicomponent alloys. It is demonstrated that regardless of an intricacy of a particular situation, there exists a simple, general, practical, and elegant expression for Pilling–Bedworth ratio underpinned by a realistic assumption. Limits of formula’s applicability are delineated.
