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 alte r their electronic state and vice versa. The d-state electrons in tran sition metal compounds/alloys are found to influence mechanical proper ties in a range of materials that include intermetallic compounds, har d metals, cryogenic alloys, etc. We have attempted to represent these effects graphically as a field map based on axes of the number of d-st ate electrons in the compounds. Specifically identifiable properties a re found in different regions in this property field map.
