Abstract

Most metallic alloys contain small concentrations of solutes because they are sufficient to achieve amazing properties on a grand scale of production and utilisation. In the early 1980s, a different concept was introduced that involved mixing large concentrations of solutes in roughly equal amounts so that there is no predominant solvent. When this happens, the degree of disorder increases and this can contribute to thermodynamic stability so that the alloy remains as a single phase in spite of the usual tendency of decomposition as solubility limits are exceeded. Whether or not this leads to properties that are unique and affordable remains to be seen, but it is clear that there are possibilities that deserve investigation.
