摘要： PROBLEM TO BE SOLVED: To provide a repair method and a repaired high-temperature part of a peripheral wall of a cooling hole of high-temperature part capable of repairing a damaged defective area around the peripheral wall of the cooling hole of high-temperature part with high precision and high quality. SOLUTION: Beveling is formed by grinding and shaping the peripheral wall of the cooling hole of temperature part, a dummy pin is inserted into the beveling so as to penetrate from a surface side of the high-temperature part to a back side, the gap between the dummy pin and the peripheral wall of the beveling is filled with a nickel base alloy brazing material, and formed by pushing and hardening so that the brazing material does not break up. Then, the dummy pin is drawn out of the molded brazing material and after forming a filled and molded brazing part where the mark of the dummy pin drawn out is a through-hole or before the dummy pin is drawn out the filled and molded brazing part is heated and sintered under a heat treatment condition holding for 2 to 24 hours at temperatures 1,080 to 1,270°C. At least a part of base metal is melted and integrated with the filled and molded brazing part, and the surplus part of the sintered filled and molded part is ground and the peripheral wall around the through-hole is shaped.

摘要： PROBLEM TO BE SOLVED: To accurately estimate the residual life of a gas turbine.

This estimation method includes a process for calculating a base line for showing the relation of the size of a grain boundary carbide with a Larson-Miller parameter(LMP) from the heating temperature and heating time of a test piece on the basis of the relational expression of LMP: LMP=(273+T) (K+logt)/1,000, and a process for estimating the metal temperature from the size of the grain boundary carbide or transgranular carbide measured from the micro-structure of the cross section of each part of an actual machine by utilizing the base line.
