| Abstract |
Soft magnetic properties of 6.5wt% Si-Fe alloy prepared by single-roll quenching technique have been studied. As surface speed of roll decreases columnar cells are formed perpendicular to ribbon surface and size of the cells becomes coarse. Thickness of sample decreases with increasing surface speed of roll. Experimental equation of thickness versus surface speed of roll may be written as D=S^(-(0.5∼0.6)), Coercive force and power loss measured at 60㎐ increase with increasing surface speed of roll. However, power loss measured at high frequencies, i.e. above 100㎐, is smaller than that at 60㎐, when surface speed of roll increases. |
