本発明は、分散強化型合金用粉末の製造方法に関するも

。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for producing powder for dispersion-strengthened alloys, and more specifically, it relates to a method for producing powder for dispersion-strengthened alloys, and more specifically, tensile strength, ductility, hardness, toughness,
The present invention relates to a method for producing powder for obtaining a dispersion-strengthened alloy with excellent heat resistance, electrical properties, and neutron irradiation resistance.
従来、分散強化型合金用粉末を製造する方法としては、
基地金属となる金属粉末と酸化物、炭化物、窒化物又は
炭窒化物等からなる硬質粒子とを混合し、これをメカニ
カルアロイング法により粉砕合金化して合金粉末を得る
という方法が行われ、既に一部で実用化されている。Conventionally, the method for producing powder for dispersion-strengthened alloys is as follows:
A method has already been used in which metal powder serving as a base metal is mixed with hard particles made of oxides, carbides, nitrides, carbonitrides, etc., and the mixture is pulverized and alloyed using a mechanical alloying method to obtain an alloy powder. It has been put into practical use in some areas.
前記従来法においては、基地金属に硬質粒子を均一に分
散させるには長時間の粉砕を必要とするという問題があ
る。また、この方法による場合、硬質粒子そのものは粉
砕工程で粉砕されることが少ないので、最初から微細な
硬質粒子を使用する必要があるが、このような微細な硬
質粒子は大量生産が困難なため非常に高価なものになる
という問題もある。The above-mentioned conventional method has a problem in that a long period of pulverization is required to uniformly disperse the hard particles in the base metal. In addition, when using this method, the hard particles themselves are rarely crushed during the crushing process, so it is necessary to use fine hard particles from the beginning, but such fine hard particles are difficult to mass produce. Another problem is that it is very expensive.
本発明は、前記従来法の欠点を除去、改善した新たな分
散強化型合金用粉末の製造方法を提供せんとするもので
ある。The present invention aims to provide a new method for producing powder for dispersion-strengthened alloys, which eliminates and improves the drawbacks of the conventional methods.

粉末表面に対する密着性をよくし、徐。Ethylene glycols and the like are preferred. When the compound before hydrolysis is an inorganic metal compound, it is formed into a gel or sol, then dissolved in water or a solvent and coated on the surface of the metal powder. Some organic metal compounds and inorganic metal compounds rapidly change into metal hydroxides or metal hydrates by hydrolysis at low temperatures such as room temperature. In such a substance, the compound particles grow large and the dispersion-strengthening particles also become coarse, so that ideal strength cannot be obtained. Therefore, by adding coating aids, etc., the reaction rate is slowed down and the adhesion to the metal powder surface is improved.

ン、窒素、酸素。It is necessary to allow the reaction to proceed. In addition, if the reaction progresses slowly, as in the case of some acetylacetonate compounds, free carbon remains, but if the residual free carbon worsens sinterability, thermal decomposition in a wet hydrogen atmosphere, etc. It is necessary to convert it into metal hydroxide or metal hydrate. At this time, if the heating rate is fast or the heating temperature is high, the oxide particles will become coarse, so it is necessary to gradually heat the particles at a relatively low temperature. The thermal decomposition temperature is preferably about 100°C to 700°C. In the case of alkoxides, etc., no free carbon remains even if they are converted into inorganic metal hydroxides by heating, etc. However, if the surface of the apricot powder is coated with an organic metal compound, etc., it is necessary to remove the free carbon.
