 note = {P(論文), Grain interior and grain boundary reactions of four types of alloys (Au-Ag-Pd-Cu alloys containing 0-40 %Au, Ag-Pd-Cu alloys with other added elements, PdCu ordered alloys with 1.5%Sn, and Ag-7%Cu alloys with 1.5%Sn) were investigated by electric resistivity measurements, hardness tests, optical microscopic observations, X-ray diffraction, and TEM. Internal strain resulting from continous precipitation did not develop to become the effective driving force of nucleation of nodules in Au-Ag-Pd-Cu alloys containing 0-40%Au. The growth rate of nodules with Sn addition was 1/18 of that in Ag-Pd-Cu alloy without Sn addition. The ordering process was found to be accelerated by addition of Sn for the PdCu ordered alloy. Retardation due to the Sn addition shows that grain interior reactions are accelerated by the Sn addition resulting in a decrease in the chemical driving force for the Ag-7%Cu alloy with 1.5Sn. It was established that grain interior hardening reactions in Ag-Pd-Cu alloys containing 40%Au were effectively accelerated by addition of Cr.},
