Summary Hardness, one of the physical properties most familiar to us, significantly affects the strength, toughness, and frictional wear of materials. Techniques to measure hardness are therefore very important in evaluating materials. While there are established techniques for measuring hardness at room and higher temperatures, there are none for measuring them at lower temperatures. The properties of hardness at low temperatures have also not been fully elucidated. My laboratory has focused its efforts on testing methods to determine the hardness of materials at lower temperatures from room temperature to extremely low temperatures (in the neighborhood of absolute zero: 4.2 K). Outcomes of the study will be used to enable the practical application of superconducting magnets to maglev trains, develop “studless” tires for snow-covered roads, and to evaluate processing methods using ice.
