The superplastic molding is performed by supplying a pressure medium to apply hydrostatic pressure and, on the other hand, removing air from the lower mold 2 through the gas vent holes 4.

超塑性金属板と同程度に成形する方法については、いま
だ開発されていないのが現状である。However, the above-mentioned superplastic forming method is limited to forming a superplastic metal plate having a specific component composition, and when attempting to deform a non-superplastic metal plate in the same way as the above-mentioned superplastic metal plate, the superplastic forming method The molded part breaks from the part pressed by the mold 1 and the lower mold 2, and sufficient molding cannot be performed. Therefore, at present, no method has yet been developed for uniformly deforming a non-superplastic metal plate as a whole to the same extent as a superplastic metal plate.

う知見を得たのである。Therefore, the present inventor conducted research on a forming method that can uniformly deform the entire non-superplastic material and form it to the same extent as a superplastic material. A superplastic metal plate is inserted between the superplastic metal plates to form a stacked plate, and the stacked plate is placed between an upper mold and a lower mold to make the superplastic metal plate superplastic. They found that even non-superplastic metal plates, which should not originally exhibit superplasticity, deform superplastically when formed under conditions that exhibit this behavior.

成形法を提供するものである。The present invention was made based on this knowledge, and includes forming a stacked plate by inserting a non-superplastic metal plate between superplastic metal plates, and forming the stacked plate into a superplastic metal plate. A method for superplastic composite forming of a non-superplastic metal plate, which is placed between a mold and a lower mold, heated to a predetermined temperature, and then deformed superplastically by applying hydrostatic pressure using a pressure medium. It provides:

ても、超塑性金属板の間に挟み込まれ、重ね合せ板の形
で超塑性複合成形すると、超塑性的に変形する原因とし
ては、つぎのことか考えられる。Even if the above-mentioned non-superplastic material should not originally exhibit superplasticity, when it is sandwiched between superplastic metal plates and superplastically composite formed in the form of stacked plates, the causes of superplastic deformation are as follows. I can think of something like that.

不可能であった成形を行うことができるものと考えられ
るのである。That is, when a non-superplastic material is subjected to superplastic deformation while being sandwiched between superplastic metal plates, the entire superplastic metal plate undergoes uniform and large deformation. It is thought that uniform stress acts on the plastic material as a whole, and as a result, deformation occurs without stress concentration, making it possible to perform molding that was impossible with conventional molding methods.

供することができる。According to the forming method of this invention, it is possible not only to form superplastic metals even with non-superplastic metals that do not originally exhibit superplasticity, but also to form wire mesh that is difficult to form using general pressure medium forming methods. , porous sintered plates, and perforated thin plates can be formed superplastically.Furthermore, it is possible to form non-porous sintered plates and perforated thin plates superplastically, which require hot-opening forming, but cannot be formed in the atmosphere because they are highly reactive metals. Even superplastic metal plates can be formed superplastically in the form of stacked plates sandwiched alternately between superplastic metal plates, so the surface can be formed without oxidation or corrosion. Industrially, it is possible to provide a very useful molding method.
