This report discusses very briefly various aspects of massive transformations in alloy systems Cu-Zn, Cu-Ga, Cu-Ga-Ge, Ag-Cd, Ag-Zn, Ag-Al, Ag-Al-Cu and Fe-Cr. In several instances a massive transformation has been shown to be an interface-controlled reaction occurring without local equilibrium at the interface. Details of transformation kinetics have been interpreted in terms of a model of the transformation interface. Nucleation has been shown to be the rate controlling process. Single crystals have been grown rapidly, utilizing the massive transformation in Ag-Al and Ag-Al-Cu alloys. Enhanced plastic flow under load has been observed in Fe-Cr alloys.
