EFFECTS OF THE COMPOSITION OF ELECTRODEPOSITED FE-NI-P ALLOY ON THE THERMOSTABILITY AND MAGNETIC-PROPERTIES

The magnetic properties, structure defects of electrodeposited Fe-Ni-P alloys with various compositions and the thermostability at amorphous state have been studied by DSC, positron annihilation and electronic integrating instrument methods. The results show that the thermostabil ity of amorphous Fe-Ni-P alloys increases with Fe content. Emergence a nd recrystallization of stable phases defer as the P content of the co ating increases. The minimum H-c, B-r and P-h occur at 9.4 P (wt pet) content. Maximum H-c, B-r and P-h occur at the weight ratio of Fe to N i equaling to 1/9.
