製造方法に関する。[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a method for producing a composite material, and in particular, the production of a tungsten plane line reinforced composite material that exhibits excellent mechanical properties at high temperatures. Regarding the method.
（従来の技術）
最近、省資源の観点からガスタービンで代表される大形
のエネルギー変換機器の高効率化が重要視されている。(Prior Art) Recently, from the viewpoint of resource conservation, increasing the efficiency of large energy conversion devices such as gas turbines has been emphasized.

が使用されているが、これらの超合金では耐用温度の上
昇の開発も限界に近い状態となっている。A basic means of increasing efficiency is increasing the operating temperature of equipment. In this case, the withstand temperature of the members used in the device becomes a structural problem. Conventionally, Ni-based, Fe-based, Co-based superalloys, etc. have been used as materials for the energy conversion equipment, but the development of an increase in the withstand temperature of these superalloys is nearing the limit.
このようなことから、次世代の耐熱材料として高融点金

中に埋め込んでて体化したものである。すなわち、Ｗ森
の高温での優れた機械的性質と、超合金の高温での優れ
た耐食性とを複合化したものである。For these reasons, attention is beginning to be paid to composite materials in which the above-mentioned superalloys are reinforced with fibers of high-melting point metal materials as next-generation heat-resistant materials. This is a material in which W wire, which is a high melting point metal, is embedded in a superalloy. In other words, it combines the excellent mechanical properties of W Mori at high temperatures and the excellent corrosion resistance of superalloys at high temperatures.

いてはＷ線強化繊維の機械的強さの劣化を招く要因とな
る欠点があった。However, in the combination of high melting point metal fibers and superalloys, interdiffusion at high temperatures becomes an important problem, whereas W is a combination with a relatively low degree of interdiffusion.
Line-reinforced Fe-based alloy composite materials have already been proposed. This combination not only has a low degree of interdiffusion between the reinforcing fibers and the superalloy, but also has the characteristic that this interdiffusion maintains proper adhesion between the two. However, even this moderate interdiffusion has the drawback of causing deterioration in the mechanical strength of the W-line reinforced fibers when used for long periods of time at high temperatures of 1200° C. or higher.
