Abstract
This paper deals with the effect of cobalt additions on the magnetic properties of Fe-W-Cr-Mo system alloy. The specimens were prepared by the powder metallurgical method.
The alloy with the additions of 15% cobalt, in which iron was substituted by cobalt, shows the best magnetic property of (B-H) max-1.25 MG-0e. when fired at 1, 375°C for 3 hrs and successively aged at 650°C for 5 hrs after sintered at 1, 400°C for 4 hr.
The precipitation of component element was observed in the electron microscopic structure.
