| 简介 |
A melt of an alloy, represented (Fe1-mTm)100-x-y-zQxRyMz, where T is Co and/or Ni, Q is B and/or C, R is at least one rare-earth element, M is selected from Al, Si, Ti, V, Cr, Mn, Cu, Zn, Ga, Zr, Nb, Mo, Ag, Hf, Ta, W, Pt, Au and Pb; 10 at %≦x≦35 at %; 2 at %≦y≦10 at %; 0 at %≦z≦10 at %; and 0≦m≦0.5, is prepared. Next, the melt is brought into contact with, and rapidly cooled and solidified by, the surface of a rotating chill roller. The melt is teemed onto a guide member, of which the guide surface defines a tilt angle with a horizontal plane, runs down on the guide surface, and then is fed through at least one tubular hole onto a contact area on the surface of the chill roller. |
