Abstract

PURPOSE:To produce amorphous alloy powder having a high apparent density and yield and excellent mass productivity by executing atomization under the specific conditions under which cooling fluid constitutes a laminar flow at the time of parting and solidifying a molten alloy by the cooling liquid. CONSTITUTION:The molten metal 2 of the alloy compsn. which is liable to become amorphous is discharged from a nozzle 3 of a tundish 1 and the molten metal flow 4 is plunged into the flow of the cooling liquid 6 under movement, by which the molten metal is parted and solidified. The flow of the cooling liquid 6 constitutes the laminar flow 7 at this time and the atomization is executed under the conditions satisfying the respective equations; d(Vc-Vm)/nu>2000, d>4X10<-3>, Vc-Vm>10, Qc/Qm>40. In the equations, (d) is the hydraulic representative diameter (cm) of the molten metal flow 4; Vc is the average velocity (m/sec) of the cooling liquid flow; Vm is the average velocity (m/sec) of the molten metal flow 4; nu is the kinematic viscosity (m<2>/sec) of the molten metal flow 4; Qc is the flow rate (kg/sec) of the cooling liquid flow; Qm is the flow rate (kg/sec) of the molten metal flow. The amorphous alloy powder having about >=30% apparent density is thereby obtd. at high yield in a large volume.
