Description
Accurate prediction of phase stability and mechanical compatibility is essential for developing metastable beta-type titanium alloys for orthopaedic applications. Current alloy design methods including molybdenum equivalence (Moeq), electron-to-atom ratio (e/a), bond order–metal d-orbital energy (Bo–Md), and the cluster-plus-glue-atom model, when used independently, often produce inconsistent predictions, especially for complex multicomponent systems. This study establishes a unified framework by systematically integrating these approaches. The evaluation of various titanium alloys shows that empirical methods facilitate rapid initial screening but lack precision, whereas electronic structure-based approaches offer greater predictive accuracy, although they require further refinement. By combining these models within a structured design strategy, prediction reliability is significantly enhanced, and inconsistencies are minimised. This framework provides a generalised methodology for designing metastable beta-type titanium alloys with improved properties, and it is adaptable to other alloy systems.
