A soft magnetic member is formed such that, when a differential relative permeability in an applied magnetic field of 100 A/m is represented by a first differential relative permeability &#x3bc;'L, and when a differential relative permeability in an applied magnetic field of 40 kA/m is represented by a second differential relative permeability &#x3bc;&#x2032;H, a ratio of the first differential relative permeability &#x3bc;&#x2032;L to the second differential relative permeability &#x3bc;&#x2032;H satisfies a relationship of &#x3bc;&#x2032;L/&#x3bc;&#x2032;H&#x2264;10, and a magnetic flux density in an applied magnetic field of 60 kA/m is 1.15 T or higher.

The invention includes: powder preparation step of obtaining magnetic core powders by mixing, of magnetic powders with thermosetting resin powders in hot state; powder filling step of filling the obtained magnetic core powders into a die; a compaction step of compacting magnetic core powders; and compact heating step of heating, compacts to the elevated temperature state at which the thermosetting resin hardens after compaction.

Method of producing powder magnetic core and method of producing magnetic core powder

A method for manufacturing a powder for a magnetic core including at least a process of performing a siliconizing treatment on a surface of an iron powder containing elemental carbon. In the process of siliconizing treatment, a powder containing at least a silicon dioxide is brought into contact with the surface of the iron powder, elemental silicon is detached from the silicon dioxide by heating the powder of silicon dioxide, and the siliconizing treatment is performed by causing the detached elemental silicon to permeate and diffuse into a surface layer of the iron powder. The invention provides a method for manufacturing a powder for a magnetic core, by which loss reduction is achieved.

A titanium alloy includes at least one alloying element whose molybdenum equivalent 'Mo' is from 3 to 11% by mass, at least one interstitial solution element selected from the group consisting of O, N and C in an amount of from 0.3 to 3% by mass, and the balance of Ti, when the entirety is taken as 100% by mass. Its content of Al is controlled to 1.8% by mass or less, and it is &#x3b2; single phase at room temperature at least.
