極低温・強磁場下での金属系構造材料の諸問題

抄録

Structural metallic materials in cryogenic engineering relating with superconducting magnets are generally used under high magnetic field and stress. However, only a few researches on cryogenic structural metallic materials have taken into consideration the effects of magnetic field on mechanical and other properties. The reason for this fact is mainly due to the lack of experimental data about the effects. It is very important to make clear the effects in order to develop widely and soundly cryogenic and superconducting technologies. In the present article, several subjects relating with the effects of magnetic field on mechanical properties, martensitic transformation and other properties mainly at cryogenic temperatures are reviewed.
