    The mechanism of tensile fracture of vacuum-evaporated gold films was observed directly in the scanning electron microscope by mounting the film on aluminum substrate, using black vacuum wax. Gold films from 1800 to 3800 Å in thickness used in this study were heated at different temperatures ranging from 100 to 800 °C. The fracture propagates at a highly localized region of plastic deformation. This deformation involves slip were clearly shown by the crystallographic nature. It was found that high tensile strains occurred only in the films thinner than about 3000 Å. The fracture length increased uniformly with increasing temperature.

    The composition of sputter-deposited HgS films was determined by electron microprobe analysis. From the relative x-ray intensity as a function of film thickness, the depth of the ionizations that produce SKαand HgMα was found to be approximately 0.65μm at an accelerating voltage of 15 kV. This value agreed well with a value calculated from Castaings' empirical law after absorption correction. The determination of film composition was limited to sufficiently thicker films than this critical value, usually 1-2 μm thick. The relation between the composition of bulk standard determined by chemical analysis and the x-ray intensity ratio was used for the correction of film composition. The results showed that the crystal structure of HgS films was independent of the composition, i.e., the growth of metastable β-HgS films was not caused by the nonstoichiometry, and that the composition of α-HgS films was not always stoichiometric, and it depended upon rf power density.

    Surface analyses of SUS 304 stainless steels haven been done by means of Auger electron spectroscopy. Impurity segregations, mainly phosphorous and sulfur, were investigated after surface treatments of heating and titanium coating. A getter effect of titanium for sulfur is investigated on the process of titanium coating, sputtering and reheating. A threshold temperature of segregation of the sulfur on the surface depends on a history of a specimen. Phosphorous segregates on the stainless steel on heating between 500 and 900 °C.
