（混合工程）
つぎに、上記Ti粉末とAl粉末とを、Al18〜50
％、Ti50〜82％の割合にて混合機で混合する。
この割合は、望ましくは、Al25.5〜43％、Ti57

処理によりつぶされる。(Densification treatment) After the degassing process, the mixture or compressed body is densified by conventional extrusion processing or hot pressing to approximately
Make it 100% density. At this time, a low temperature (for example, 400
℃). The purpose of performing this densification treatment is to prevent the Ti powder and Al powder from adhering to each other, to facilitate the alloying reaction during the high-temperature/high-pressure treatment described below, and to obtain a densified member. If the product shape can be formed by extrusion processing or hot pressing, for example, a rod, a tube, a rectangular parallelepiped, or a shape similar to these, it is formed into that shape during densification treatment (dense body) (high temperature, high pressure treatment process) The dense body is heat treated at high temperature and high pressure. In other words, by diffusing Al into Ti, Ti−
Forms Al-based intermetallic compounds. At this time, many pores are generated due to the Kirkendall effect, that is, diffusion of Al, forming cavities, but these cavities are crushed by high pressure treatment.

封入して圧力を加えることが必要である。 This process is, for example, HIP (Hot Isostatic Pressing)
This is done in processing. The temperature of HIP treatment is 400℃
Perform in the range of ~1400℃. This is because if the temperature is below 400℃, the formation of intermetallic compounds between Ti and Al will not proceed.
On the other hand, this is because the material melts at temperatures above 1400°C. Furthermore, at temperatures between 400°C and 1400°C, the reaction between Ti and Al proceeds rapidly, creating many cavities and creating a porous body. Therefore, it is necessary to encapsulate the mixture and apply pressure to collapse the cavities. is necessary.
この処理により、TiAlおよびTi3Alの金属間化
合物が形成されるが、このとき、Tiの割合が大
きい場合に、Ti3AlをマトリクスとしてTiAlが分
散状態になり、一方、Tiの割合が少ない場合に
逆になる。 This treatment forms intermetallic compounds of TiAl and Ti 3 Al. At this time, when the proportion of Ti is large, TiAl becomes dispersed with Ti 3 Al as a matrix, while when the proportion of Ti is small The case is reversed.

Nb0.1-5% and B0.05-3%. Below the lower limit of any element, no effect of improving ductility is observed, and above the upper limit, the effect of improving ductility is almost saturated, and the strength properties also decreases.

At this time, if the density is less than 60%, the shape of the compressed body cannot be maintained after compression, and if the density is more than 95%, the degassing treatment cannot be effective.

This process is applied when the product shape is complex and cannot be formed by extrusion or hot pressing. Near Net
Shape forming is performed because Ti-Al intermetallic compounds are extremely hard, so once they are formed, it is extremely difficult to further shape them. It is then molded into a shape close to the desired product shape.
