Abstract
A study on non-destructive technique for creep damage of type304 stainless steel was performed. In this study, we concentrated on the magnetic field change with creep damage. This technique has a possibility that the damage before crack initiation is detected. We report that the results on the magnetic field change during creep damage progress, in order to examine the applicability of this technique based on magnetic field change to time-dependent damage. Though type304 stainless steel is a paramagnetic material, the leakage flux density of creep damaged specimen changes obviously, as compared with that of aged specimen.
