摘要： PROBLEM TO BE SOLVED: To provide a method for diagnosing the life of a component, which can diagnose the life of a component highly precisely in accordance with a degree of creep damage estimated probabilistically and a degree of thermal fatigue damage estimated probabilistically, and which can quickly diagnose the life of a component that is exposed to high temperatures. SOLUTION: Approximation of a degree of creep damage is performed for each component according to a relational expression including a Larson-Miller parameter. According to an approximate expression obtained by determining a constant for each component, a degree of creep damage of that component is determined. By performing a Weibull statistics analysis on this degree of creep damage, a degree of creep damage is probabilistically estimated. Further, by performing a Weibull statistics analysis on a degree of thermal fatigue damage calculated according to an approximate expression for approximation of a degree of thermal fatigue damage, a degree of thermal fatigue damage is probabilistically estimated in a similar manner.

摘要： PURPOSE:To measure the hardness of the peripheral wall of a center hole having a small inner diameter with high reliability, by inclining a hardness meter with respect to a measuring surface. CONSTITUTION:A hardness meter fixing apparatus 1 is arranged to the center hole 3 of a turbine rotor 4 in a manner movable to the longitudinal direction thereof. The apparatus 1 has wheels 5 and can be held so that the horizontal surface 1a thereof is inclined and the angle theta of inclination of the horizontal surface 1a is detected. The angle theta is displayed on an angle display device 7a through a cable 6a and inputted to an operation apparatus 9 by a cable 8a. Further, a hardness meter 2 is provided to the horizontal surface 1a and a pressure element is pressed to the peripheral wall 3 of the center hole under the constant pressure of a spring to form a cavity. When the pressure element is not brought into contact with the peripheral wall, vibration frequency is constant but changes during the penetration of the pressure element under pressure. If the peripheral wall 3 is soft, the cavity is large and the change in the frequency becomes large. The hardness meter 2 accurately detects the change in the frequency to display the same on a hardness display device 7b through a cable 6b. The apparatus 9 corrects the hardness of the angle theta on the basis of preliminarily calculated function to display true hardness on a digital hardness display device 10.
