The property changes of the alloy containing two rare earth elements AgLaY during cold forming and the high temperature softening-resistance during annealing were studied using Vickers hardness tester. The distribution and action of the rare earth elements in Ag-alloy were also analyzed. Experimental results show that AgLaY alloy has more remarkable work-hardening effect than AgLa and pure silver, and it also has better thermal-resistance. The effects of RE elements, La and Y, on the properties of Ag-alloy are attributable to their symbiotic distribution and complementary function. Because of the common properties of La and Y as RE elements, they have the completely similar distribution in Ag-alloy. At the same time, La and Y make full use of complementary role in the alloy since they belong to different periods in periodic table and have differences in atomic structure and properties.展开更多

An Ag alloy thin film (additive element Pd, Cu, P) was created on glass substrates, and various heat treatment was conducted. Then, fine structure was observed on this thin film using AFM, and fine structure evaluation of the inside was carried out by the in-plane diffractometry and X-ray diffractometry, and in addition, residual stress analysis was carried out. These results were compared and were examined, and fine structure and physical property in a metallic thin film were evaluated, and usefulness of evaluation method was verified.展开更多
