Correlations between the electronic state and mechanical properties of some transition metal compounds/alloys

It is observed that changes in the mechanical state of solids can alter their electronic state and vice versa. The d-state electrons in transition metal compounds/alloys are found to influence mechanical properties in a range of materials that include intermetallic compounds, hard metals, cryogenic alloys, etc. We have attempted to represent these effects graphically as a field map based on axes of the number of d-state electrons in the compounds. Specifically identifiable properties are found in different regions in this property field map.
