本発明は、析出強化型合金を用いた恒温鍛造用金型にお
ける熱処理に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to heat treatment in isothermal forging dies using precipitation-strengthened alloys.
恒温鍛造用金型は、鍛造温度によって使い分けが行われ

合物を析出し、高温強度を得る析出強化型合金である。Isothermal forging dies are used depending on the forging temperature, and when the temperature is 700 to 800°C, Ni-Cr-C is used.
O-based single-base alloy, former -^51) (product of Mitsubishi Metals), is often used. After heating to 840°C, solid solution strengthening of Crt Co + Mo occurs by air cooling, and after further heating to 760°C, It is a precipitation-strengthened alloy that precipitates an intermetallic compound of AZl Ti by air cooling and obtains high-temperature strength.
したがって、本合金を所定の金型形状に仕上げた後、前

の後、離型及び潤滑を目的としたセラミックス皮膜を形
成させていた。セラミックス皮膜の形成手段としては、
スパッタ法、イオンブレーティング法等である。Therefore, after finishing the present alloy into a predetermined mold shape, the aforementioned solid solution strengthening treatment and precipitation strengthening treatment were performed, and after polishing, a ceramic film was formed for the purpose of mold release and lubrication. As a means of forming a ceramic film,
These include sputtering method, ion blating method, etc.
しかし従来の方法では、セラミックス皮膜の形成温度を

せた金属間化合物がＩｎ大化し強度劣化を起こすため、
セラミックス皮膜の形成温度は７６０℃以下に抑えなけ
ればならず、手段としてはスパッタ法または、イオンブ
レーティング法に限られている。However, in the conventional method, if the ceramic film is formed at a temperature of 800°C or higher, the intermetallic compound precipitated by the precipitation strengthening treatment becomes larger in In and causes strength deterioration.
The temperature at which the ceramic film is formed must be kept below 760° C., and the methods used are limited to sputtering or ion blasting.
（ｉ！ｇ題を解決するための手段）
上記課題を解決するために本発明は、Ｉｕ４Ａから金型

セラミックス皮１１１Ａを形成するものである。(Means for solving the i!g problem) In order to solve the above problems, the present invention provides that after forming a mold shape from Iu4A, any of the heat treatment steps of solution treatment, solid solution treatment, and precipitation strengthening treatment is performed. During the heat treatment process,
This forms a ceramic skin 111A.
このように本発明方法によれば、セラミックス皮膜の形
成温度を、溶体化処理温度、あるいは固溶体化処理温度
に合わせ、これらの熱処理と同時にセラミックス皮膜を
形成することができる。As described above, according to the method of the present invention, the ceramic film formation temperature can be matched to the solution treatment temperature or the solid solution treatment temperature, and the ceramic film can be formed simultaneously with these heat treatments.
すなわち、セラミックス皮膜の形成温度を熱処理温度に
合わせることから、一連の熱処理の効果を何ら１員なう
ことなく、又、熱処理と同時に皮膜形成を行なうので、
工程の省略化が達成されるものである。In other words, since the temperature at which the ceramic film is formed is matched to the heat treatment temperature, the effects of the series of heat treatments are not affected in any way, and because the film is formed at the same time as the heat treatment,
The process can be simplified.
