Abstract: A magnetic powder contains at least the first alloy powder and the second alloy powder in which those composition are different. The second alloy powder has a smaller median diameter than the first alloy powder and contains Cr of 0.3-14 at %. The first alloy powder has a Cr content of 0.3 at % or less. With respect to the total sum of the first alloy powder and the second alloy powder, a content of the second alloy powder is 20-50 vol % and the ratio of the median diameter of the first alloy powder to the second alloy powder is 4-20. The first alloy powder comprises either an amorphous phase or a crystalline phase having an average crystallite size of 50 nm or smaller. Thereby, a magnetic powder having low magnetic loss and good corrosion resistance without damaging insulation resistance and saturation magnetic flux density can be realized.

Abstract: A method for creating a metallurgic component comprises creating a thin-walled container corresponding to a shape of the metallurgic component from a metal. If powder metal is not already in the container (depending on a method of creating the container), the thin-walled container is filled with powder metal. A quick-can device is fixed to the thin-walled container, and the powder metal is consolidated inside the thin-walled container (e.g., in a hot isostatic press). During consolidation, pressure within the thin-walled container is monitored and a desired pressure differential between an inside of the thin-walled container and an outside of the thin-walled container is maintained by the quick-can device.
