Method of heat treatments of amorphous alloy ribbons |
| 摘要 |
A method of heat treatments of amorphous alloy ribbons comprises the sequential steps of; grinding amorphous alloy ribbon continuously fed at a predetermined speed (V) selectively varied in the range of 1 cm/sec</=V</=50 cm/sec, to uniformly finish the ribbon, and successively, heat-treating the ribbon with its surface contacting a stationary or rotating heating body having a surface temperature (T) defined in the range of (Tcry-200 DEG C.)</=V</=(Tcry+50 DEG C.), where Tcry is a crystallization point temperature of the alloy, to uniformly enhance the magnetic properties of the ribbon, and to remove the specific curlings inherently caused by so-called splat cooling manufacturing method, without causing any developments of brittleness of the ribbon mentioned above.
