| Research Abstract |
Purpose of this study was determination of grain boundary thickness and etc. using a laser interferometer, and physical properties of ice with fine grain size. Laser interferometer was only carried out stability of equipment. Making of ice samples with fine grain size, 0.01mm order, were success by ice phase transition. Uniaxial creep tests were carried out using the fine grain ice samples. The temperature and stress conditions were test parameters. Strain rate at 10% strain is several 100 times faster than normal grain size ice. And minimum stain rate does not appear for cold temperature test conditions. It normally appears around several present of strain. These result suggest that grain boundary strongly affect to deformation of ice.
