Abstract
PURPOSE: To realize a measurement of the residual life, by measuring the change of the ultrasonic attenuation constant and thus detecting the degree of deterioration of the metal material in a nondestructive way and according to the lapse of time.
CONSTITUTION: The ultrasonic attenuation constant of the metal material is measured. This constant is applied to the relation curve chart between the change of the heating time and the heating temperature under the stress of the known metal material and the change of the ultrasonic attenuation constant. As a result, both the void occurrence and the life can be presumed.
