Much attention has recently been paid to ODS in many industrial fields, such as aerospace generation, and automobile as a new material having excellent characteristics, such as high creep strength and high heat resistance. However it has not been put into practical use yet because the material has some weak points also, such as low ductility at room temperature and poor workability. Therefore, establishment of forming process of the material is necessary to put the material into practical use. Isothermal forging is worthy of remark as a forming process of this material. However, there are some obstacles to overcome for establishment of this method as a forming process of the material. The purpose of this study is to prove the usefulness of the isothermal forging as a forming process of ODS though various experiment, and to provide fundamental informations about techniques for making use of this method.
