摘要： A process for manufacturing amorphous alloy powders is provided, wherein, a high-speed fluid jet is blown against a flowing melt of an alloy which can be formed into amorphous powders, thereby powerizing the melt and rapidly cooling and solidifying the melt. Use is made of an action tube (4) in which pressure is reduced and turbulent flow is caused so as to increase the cooling rate of the powderized alloy and to form particles of irregular shape. Further, the powderized alloy particles are forced to forcibly collide against a block to increase the cooling rate of the alloy and to form particles of irregular shape.
