この発明は、従来よりも低い鍛造力で成形することので
きる恒温鍛造法およびその恒温鍛造法で用いる潤滑シー
トに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a constant temperature forging method that allows forming with a lower forging force than conventional methods, and a lubricating sheet used in the constant temperature forging method.
一般に、Ｔｉ基合金、Ｎｉ基合金等の難加工材を成形す
る方法として金型を被加工材と等温に保持して鍛造する
恒温鍛造法があることは良く知られているところである
。この恒温鍛造法は予備成形から最終成形まで同じ金型
で一工程で成形することかできる可能性かあるところか
ら盛んに研究がなされているか、金型の温度を難加工性
被加工材と同等の温度に保持して高温で鍛造するために
、金型にとっては非常に苛酷な条件での使用となり、か
かる苛酷な条件て使用てきる金型の価格は非常に高価な
ものであるにもかかわらず使用寿命が短いので恒温鍛造
製品は一般に高価なものとなり、特殊な部品の製造にの
み使用されている。Generally, it is well known that as a method for forming difficult-to-process materials such as Ti-based alloys and Ni-based alloys, there is an isothermal forging method in which a die is held at the same temperature as the workpiece. This isothermal forging method has been actively researched because it has the possibility of forming everything from preforming to final forming in the same mold in one step. The molds are used under very harsh conditions because they are held at a temperature of Because of their short service life, isothermal forged products are generally expensive and are only used to make special parts.
さらに、上記恒温鍛造は高温で低ひずみ速度で鍛造され
るために（例えば、Ｎｉ基超塑性合金を被加工材として
恒温鍛造するには、１０００℃以上の温度でＩＱ’ｓ−
’程度の低ひずみ速度で鍛造する）、被加工材と金型と
の間に拡散接合が極めて起こりやすく、かかる拡散接合
が起こると恒温鍛造力の大幅な増加をもたらし、好まし
くない。Furthermore, since the above-mentioned isothermal forging is forged at a high temperature and a low strain rate (for example, in order to isothermal forge a Ni-based superplastic alloy as a workpiece material, IQ's -
When forging is carried out at a low strain rate of about 100 lbs.), diffusion bonding is extremely likely to occur between the workpiece and the die, and when such diffusion bonding occurs, it results in a significant increase in isothermal forging force, which is undesirable.
かかる拡散接合の発生を防止するために、従来から金型
と被加工材の間にケイ酸ガラスなどの潤滑剤を介在させ
て鍛造しているが、特に高温高圧下に比較的長時間保持
される恒温鍛造下においては、上記公知のケイ酸ガラス
などの潤滑剤では潤滑剤切れによる拡散接合か起こりや
すいという問題点があった。In order to prevent the occurrence of such diffusion bonding, a lubricant such as silicate glass has traditionally been interposed between the die and the workpiece during forging, but this is especially true when the material is held at high temperature and pressure for a relatively long period of time. Under constant-temperature forging, there is a problem in that diffusion bonding is likely to occur due to the lubricant running out when using a lubricant such as the above-mentioned known silicate glass.
また、上記拡散接合が防止されても、被加工材と金型の
せん断摩擦係数か恒温鍛造圧力に大きな影響を与えるこ
とが知られており、恒温鍛造力の増加を防止するために
」二記せん断摩擦係数を小さくする必要があるが、従来
のケイ酸ガラスなどを潤滑剤として用いる程度では十分
な効果が得られていない。In addition, even if the diffusion bonding described above is prevented, it is known that the shear friction coefficient between the workpiece and the die has a large effect on the isothermal forging pressure. It is necessary to reduce the coefficient of shear friction, but the use of conventional silicate glass or the like as a lubricant does not provide sufficient effects.
そこで、本発明者等は、かかる問題点を解決すべく研究
を行った結果、
被加工材と金型の間に、ケイ酸ガラスなどの潤滑剤とと
もに金属箔を介在させて恒温鍛造すると、従来よりも被
加工材と金型とが拡散接合することが少なく、かつせん
断摩擦係数も小さくなるために従来よりも低い恒温鍛造
力で鍛造することができるという知見を得たのである。Therefore, the present inventors conducted research to solve these problems, and found that isothermal forging with a metal foil interposed between the workpiece and the mold together with a lubricant such as silicate glass has improved the conventional method. They found that there is less diffusion bonding between the workpiece and the die, and the shear friction coefficient is also smaller, making it possible to forge with a lower isothermal forging force than in the past.
この発明は、かかる知見にもとづいてなされたものであ
って、
被加工材を金型に装入して恒温鍛造する方法において、
上記液加り材と金型との間に、潤滑剤とともに金属箔を
介在せしめる恒温鍛造法に特徴を有するものである。This invention was made based on this knowledge, and includes a method for isothermal forging by charging a workpiece into a mold,
This method is characterized by a constant temperature forging method in which metal foil is interposed along with a lubricant between the liquid-added material and the mold.

の合金からなり、被加工材と同等またはそれ以下の強度
を有する金属箔がよく、温度、使用条件により選択する
必要かあり、その厚さは１０〜１００μｍが好ましい。The number of metal foils interposed between the workpiece and the mold together with the lubricant is usually one or two or more, and in the case of two or more, the metal foil and the metal foil are It is more preferable to interpose a low viscosity boric acid glass lubricant between the two. Metal foils are preferably made of Ti, A, Q, Fe, and their alloys, and have a strength equal to or lower than that of the workpiece, and should be selected depending on the temperature and usage conditions. 10 to 100 μm is preferable.

層向上する。To interpose a lubricant and metal foil between the workpiece and the die, prepare a metal foil with lubricant uniformly applied on both sides as a forging lubricant sheet, and use the forging lubricant sheet during forging. By taking out the metal foil and interposing it between the workpiece and the metal foil and forging at a constant temperature, the forging process becomes easier, and the work efficiency is further improved because it eliminates the need to apply lubricant by spraying.

ともわかる。From the results in Tables 1 and 2, it is clear that according to the isothermal forging method of the present invention, the shear friction coefficient is smaller than that of the conventional method, and the isothermal forging force can be reduced, and furthermore, it is better than when using a single sheet of metal foil. It can also be seen that the shear friction coefficient and constant temperature forging force can be further reduced by using two metal foils.

By inserting a metal foil with a smoother surface than these between the workpiece and the mold together with a lubricant, the contribution of fluid lubrication increases, and the metal contact area between the workpiece and the metal foil, and the mold and the metal foil. This decreases the shear friction coefficient, and if the metal foil itself is flexible, it acts as a solid lubricant, which can significantly reduce the frictional resistance between the workpiece and the mold.

By doing so, the contribution of fluid lubrication increases, the shear friction coefficient further decreases, and these metal foils form pseudo-parallel surfaces, and the lubricant layer between them approaches perfect fluid lubrication conditions. Frictional resistance can be greatly reduced.

Therefore, it is possible to reduce the load on the die and extend the life of the die, and it also improves the ease of removing the die, which makes it possible to significantly reduce isothermal forging costs compared to conventional methods. It brings about excellent industrial effects.
