Influence of Silicon Content on Microstructure and Damping Capacity of Fe-Cr Based Damping Alloy

Abstract:

Five kind of Fe-12.8Cr alloys with different silicon content which were respectively 0%, 0.2%, 0.5%, 0.9% and 1.2% were experimentally made, and the microstructure and damping capacity of the alloys in quenched were studied. Explains the effect of the silicon content on Fe-Cr alloy damping performance, the results shows that the silicon content affects obviously on damping properties of Fe-12.8Cr two element alloy, Fe-12.8Cr two element alloy can be with better damping properties when the silicon content is about 0.6%.The domain area and domain interface mobile ability affect on the damping performance of Fe-Cr two element alloy, which ensure the appropriate grain size to increase the domain area and improve the magnetic domain wall moving ability can improve the damping properties of Fe-Cr based alloy.
