摘要：
A method of manufacturing a material for a rotary machine component, by performing at least a solution treatment on a material made of a duplex stainless steel, wherein, in the solution treatment, the material is heated to a temperature in a range of 950 to 1100° C. and is thereafter cooled to 700° C. at an average cooling rate of equal to or greater than 20° C./min.
