Abstract
Thin films of single-phased alloys of the normally immiscible metals, molybdenum and gold, have been prepared by vapour co-deposition onto cool substrates. The microstructural changes induced by heating were studied by electron diffraction and electron microscopy which revealed that the alloys decomposed into a two-phase aggregate of molybdenum and gold by precipitation both within the films and on the free surfaces. Eventually the gold was entirely removed from the specimens. Electrical resistance measurements indicated that the decomposition process obeyed second order kinetics and was associated with an activation energy that increased as the transformation proceeded.
