摘要
The aim of this work is to provide experimental results in order to understand internal stress and grain-size effects on the magnetic properties of high-purity polycrystalline nickel. In situ experiments under a loading-unloading monotonous tensile test have shown a strong degradation of the magnetic properties in the elastic state. The elastic-plastic transition and the effect of grain size can be highlighted thanks to Barkhausen noise measurements.
