Preparation of amorphous powders of Ni_<75>Si_8B_<17>, Co_<72.5>Si_<12.5>B_<15> and Fe_<75>Si_<10>B_<15> ternary alloys was tried by atomization of their molten metals using a twin roller technique. Atomization was achieved by feeding a stream of molten metal between rapidly rotating rollers with a carbon paste and the disintegrated molten metals were quenched into the water bath. In this paper the critical conditions for atomization were examined using Ni_<75>Si_8B_<17> alloy and the relationship between the volume fraction of amorphous phase and the powder size was clarified. The results suggested that powders with an amorphous single phase might be produced by improvement of this method.
