Density decoding technique to optimise the constitution/composition of alloy

[rathorebc]

Respected Members,

The density (Specific Gravity) is a valuable index of chemical composition of alloys. Although, one can calculate the composition of binary alloys of known metals from their densities (Specific Gravities) in straight forward manner, but for alloys having three or more constituents it leads to a mathematically untenable situation as we have more unknowns than the equations. The densities of such multi-component alloys are always associated to a large number of probable compositions. So, mathematically it is not possible to calculate all such probabilities and then to point out authentically with certainty as to which one particular composition does actually belong to the given alloy.

 

We are making an attempt to establish that the ‘Archimedean method’ still holds good and may be employed successfully to determine the compositions of multi-component alloys by decoding their densities into percent elemental compositions, even without prior knowledge of constituent metals. It further suggests that the densities of alloys hold the characteristic feature – the fingerprints of alloys which may be decoded for forecasting the presence of elements and their compositions in n-component alloys.

 

The Software program successfully decoded the densities of alloys into elemental percent compositions without previous knowledge of constituent metals if the constituent metals present in such alloy are initially selected in program. In other words, the program originally initialized for Au, Ag, Cu and Zn could successfully decode all densities of binary alloys containing Au-Ag, Au-Cu, Au-Zn, Ag-Cu, Ag-Zn and Cu-Zn; ternary alloys containing Au-Ag-Cu, Au-Cu-Zn and Ag-Cu-Zn as well as all quaternary alloys containing Au, Ag, Cu and Zn but It produces inaccurate results if any other metal is present in such alloy except Au, Ag, Cu and Zn.

 

We are making our sincere efforts to compare our theoretical data with experimental results. Our findings are likely to publish in forthcoming issue of 'Material Letters', a scientific journal of International repute i. e. The Elsevier Publications.
