Abstract
The variations of the grain-boundary precipitates, the electrical resistivity, and the magnetization of a Ni-8 at. % Sn alloy have been investigated as functions of annealing temperature and annealing time. For samples annealed at 773 K, the averaged growth rate of the size of the grain-boundary precipitates is roughly 0.42 μm/h for the first 24 h; the electrical resistivity at T=10 K and the magnetization at T=10 K and H=5 kG vary monotonically with respect to the annealing time for the first 2 weeks, changing from 22.5 to 7 μΩ cm for the electrical resistivity and from 27 to 33 emu/g for the magnetization. A large tail section in the magnetization versus temperature curve was also observed in the aged samples. All these electrical and magnetic variations in the Ni-8 at. % Sn samples annealed at 773 K varied monotonically with respect to the growth of the grain-boundary precipitates.
