Abstract
The variations of the electrical resistivity, the magnetization, and the grain boundary precipitates of a binary NiSn alloy system with Sn content up to 8 at% are investigated as functions of the annealing time at 773 K. For samples homogenized at 1325 K, clear grain boundaries are observed; the residual electrical resistivity is increased roughly by 2.81 μΩcm per at% of Sn and the Curie temperature is found to decrease roughly 32.5 K per at% of Sn. However, for these aged samples both, grain boundary precipitates and variations of the electrical resistivity and the magnetization, are observed, the binary alloy with higher Sn content has the higher variation rate in the decrease of the electrical resistivity, the increase of the magnetization, and the growth of the grain boundary precipitates.
