Single intermetallic compound formation in Pd-Pb and Pd-Sn thin-film couples studied by X-ray diffraction

Interfacial reaction has been found to occur at room temperature in both Pd-Pb and Pd-Sn thin-film couples, and the compounds formed are PdPb2 and PdSn4, respectively. Structural information and compound formation rate were obtained by X-ray diffraction. These reactions indicate single-compound formation in thin-film diffusion couples and the prediction of the first compound phase to grow in a diffusion couple is discussed. © 1982.
