The present invention relates to a method to evaluate deterioration of a material using an ultrasonic wave and, more specifically, relates to a method to evaluate deterioration and a degree of damage of a metal material or the like constituting a component, a device, or the like used in a high temperature environment for a long time using an ultrasonic wave damping value. According to the present invention, provided is the method to evaluate deterioration by analyzing sediment within a metal material isothermally changed using the ultrasonic wave damping value which evaluates a degree of deterioration of a material constituting a device, a component, or the like used in the high temperature environment for a long time with a precise and simple method; without destroying the device, the component, or the like. |
