Quenched-in Vacancy in Solid Solution Alloys

概要

From the difference in the electrical resistivity change induced quenching between pure Au and Au-Pd solid solutions, the binding energy for a vacancy and a solute atom was determined. The rate of decrease of quenched.in additional resistivity with decreasing temperature in the alloy was more rapid than in the pure metal and the resistivity after quenching was smaller than that before quenching in high concentration alloys below a certain quenching temperature. It was concluded that the interaction of a Pd atom and a vacancy in Au-Pd alloys was attractive, which formed a contrast with the expectation of Lazarus theory, and an additional resistivity the solute atom was canceled partly the binding of the vacancy. In Ag-Pd alloys the same results would be expected.
