説明

Cryogenic engineering is one of important high technologies. Research and development of superconducting systems has accelerated the studies on structural materials for low temperature use. Mechanical properties of the materials at liquid helium temperature are unique as well as essential for the design and the reliability of cryogenic machinery. The deformation and fracture behaviors of structural materials in liquid helium are reviewed. Chaotic behaviors in the discontinuous deformation are characteristic of fractal in the distribution of plastic deformation. Dimple pattern on fractured surface has also fractal in the randomness of the distribution. The reliability of the cryogenic machinery and systems depends upon the properties of structural materials. Now, the fundamental research of the materials has been promoted and R & D for new materials and the evaluation has been carried out internationally.
