| Research Abstract |
In this study, in order to clarify a high temperature deformation behavior of heat resistant structural materials, a helical spring creep testing method as an ultra low strain rate creep test was developed. Furthermore, the high temperature deformation behavior of tin alloys, aluminum alloys, austenitic stainless steels and ferritic heat resistant steels were investigated. As these results, we could obtain clear helical spring creep curves, and get the high temperature deformation behavior at ultra low strain rate which is 100 times lower than uniaxial tensile creep testing method.
