<P>PROBLEM TO BE SOLVED: To provide a soft magnetic alloy consolidation object capable of being preferably used as a magnetic core for a motor for an electric automobile, a hybrid car or the like, and to provide a manufacturing method for the soft magnetic alloy consolidation object. <P>SOLUTION: The soft magnetic alloy consolidation object is manufactured by treating at least one kind of amorphous alloy powder by a pressure molding. In the compact, the amorphous alloy powder of 50 to 99 vol.% has an insulator film on its surface while using the whole volume of the amorphous alloy powder as a reference, and the amorphous alloy powder of 1 to 50 vol.% does not have the insulator film on its surface in the amorphous alloy powder. The manufacturing method contains a process (1) in which powder having no insulator film on the surface of the amorphous alloy powder and powder having the insulator film on the surface of the amorphous alloy powder are mixed so that each content reaches 1 to 50 vol.% and 50 to 99 vol.%, while using the whole volume of the amorphous alloy powder as the reference. The manufacturing method further contains the process (2) treating powder obtained in the process (1) by the pressure molding. <P>COPYRIGHT: (C)2007,JPO&INPIT |
