Abstract
We propose for the first time, a quantitative thermodynamic explanation for the formation of solid-solutions of immiscible elements by mechanical alloying. It is shown how codeformation of a hard and a soft phase results in the formation of disc or needle shape particles possessing large aspect ratios. As the particle size drops to about 10nm with continued deformation, the particle tips and edges generate nanometer size fragments upon subsequent necking. Using simple thermodynamic arguments we show how otherwise immiscible atoms of these fragments will enter in solution and that this process can lead to their full dissolution.
