Abstract

New results on mixing in single layered metal structures exposed to nanosecond high power ion beams (HPIB) are presented. Au/Cu and Cu/Mo structures have been investigated using RBS, SIMS, AES and transmission electron microscopy. It is shown that HPIB-induced mixing was initiated at the substrate-deposited-layer interface in contrast to laser melting which starts at the surface. Cu3Au superstructure phase, CuAu metastable state and an amorphous structure have been revealed. Cu/Mo structures which cannot produce equilibrium alloys and compounds and strongly differ in their thermophysical properties, can be mixed in the gaseous and liquid phases by three HPIB pulses with 0.95 J/cm2 energy density.
