Abstract
A comparative experimental study of self-sustained exothermal waves in electrodeposited amorphous antimony (Sb) films, quenched glassy copper-titanium (CuTi) alloy, and magnetron deposited multilayer nickel-aluminum (Ni/Al) films was accomplished using a single approach. It is shown that self-propagating thermal waves can be initiated in all three systems, which convert the amorphous or multilayer metallic structure into nanocrystalline materials. The normalized temperature-time profiles allow us to make a conclusion on the similarity of the processes, despite the diverse driving forces in the considered systems. Periodic microstructures, probably induced by thermal oscillations of the crystallization waves, were observed in Sb and CuTi samples and discussed from the viewpoints of theoretical models.
