    摘要： Provided is a process for improving alloy properties which can improve the high-temperature ductility of a Ni-base heat-resisting alloy while maintaining its excellent high-temperature strength and weldability. Specifically, it relates to a process for the heat treatment of a Ni-base heat-resisting alloy having a specific composition which comprises the steps of subjecting the alloy to a first-stage solution treatment by keeping it at a specific temperature for a specific period of time; cooling the alloy to a second-stage solution treatment temperature at a specific cooling rate; subjecting the alloy to a second-stage solution treatment by keeping it at a specific temperature for a specific period of time; cooling the alloy rapidly to room temperature at a specific cooling rate; subjecting the alloy to a stabilizing treatment by keeping it at a specific temperature for a specific period of time; cooling the alloy rapidly to room temperature at a specific cooling rate; and subjecting the alloy to an aging treatment by keeping it at a specific temperature for a specific period of time.
