As a representative example thereof, an Fe-based particle-dispersed alloy is known, and this Fe-based particle-dispersed alloy is generally manufactured by a method shown in FIG. That is, the raw material powder is processed by a device having a pulverizing energy of about 0 to 20 g (g is a dynamic acceleration) such as a high energy ball mill to produce a mechanical alloying (MA) powder.

言う問題があった。The most important thing in this manufacturing process is how to proceed alloying quickly to produce a high quality MA powder in which ceramic particles are uniformly dispersed. For this purpose, it is most important to examine and manufacture the first raw material powder. Conventionally, as a raw material powder of an Fe-based particle-dispersed alloy, a raw material powder called elementary powder mixed powder obtained by mixing Fe powder, Cr powder, W powder, Ti powder and ceramic particles, or a product composition containing these metal elements An alloy powder in which an alloy powder is produced and mixed with ceramic particles has been widely used. However, in the raw powder mixed powder, the MA processing time of each raw powder is different, and in particular, the diffusion of W (tungsten) is slow, so that not only the processing time becomes long, but also a high quality MA powder which absorbs a large amount of oxygen during the processing. There was a problem that was not obtained. In the case of alloy powder, since the powder itself is hard, the wear of the container, ball or rotor of the high-energy ball mill is increased during processing, and not only is the MA powder contaminated by the wear material, but also the life of the equipment is shortened. There was a problem of becoming.
