摘要：PROBLEM TO BE SOLVED: To provide a turbine blade manufacturing methodcapable of improving a quality of a brazing portion.SOLUTION: The method includes: abrazing step of actuating a heater, performing heating at a first temperature, andmelting a brazing material to unite with a base material while arranging the base materialof a turbine blade in which the brazing material is arranged in a predetermined heatingfurnace having a heater; a slow step of lowering an in-furnace temperature and coolingthe base material by stopping the heater after the brazing step; and a solution treatmentstep for improving ductility of the base material by heating the base material at secondtemperature lower than the first temperature after slow-cooling.SELECTED DRAWING:Figure 1
