概要
- 論文の詳細を見る
High temperature deformation and fracture of Fe-Co and Fe-Cr alloys have been studied in connection with the magnetism. The flow stresses of both alloy systems increased with increasing the solute contents at ferromagnetic temperatures below the Curie temperature while they were independent of the solute contents at the paramagnetic temperatures. Therefore, the solid solution strengthening observed in this study is closely related to the ferromagnetism. Furthermore, the fracture strain in the ferromagnetic temperature region was about 10% larger than that in the paramagnetic temperature one. These findings indicate that the magnetic strengthening originating from the magnetism produces high strength, high ductility and high thermal stability.
