Ion backscattering, Auger electron spectroscopy, x-ray microanalysis, and scanning and transmission electron microscopy have been used to investigate the structural-phase state of an alloy formed by pulsed fusion in a system consisting of a Ta film on an Fe substrate when exposed to a microsecond pulse of a low-energy, high-current electron beam. The structure that is formed has a complex phase composition, and the structure varies with depth. This structural nonuniformity reflects a decrease of Ta concentration with increasing depth as a consequence of its diffusion in the liquid phase, as well as a difference between the cooling rates on the surface and in the deeper layers of the melt.
