Abstract

FeCo-2V (Permendur) is one of magnetostirictive alloys, and this alloy is a candidate material for application of vibration energy harvesting. Since their magnetic properties depends on their microstructure, the magnetic properties such as magnetization, magnetostiriction and inverse magnetostriction should be investigated in materials prepared by different processes. In this study, the magnetic properties of FeCo-2V alloy sheets with the different microstructure obtained from a bar were studied, in order to understand influences of the microstructure on the magnetic properties. The results showed that crystalline grains in alloy sheets cut from the bar grow with increasing temperature, while grains in hot-rolled alloy sheets do not grow so much by annealing. It was also shown that inverse magnetostriction in well-annealed alloys reveal good vibration power generation property, and the texture in hot-rolled alloy sheets seems to be unfavorable to the vibration power generation property.
