摘要
A heat treatment method for an additively manufactured object which is formed from a laminated Ni-based alloy includes: a heat treatment step to optimize carbide deposition in the form of heating the additively manufactured object for 1 hour or more and 100 hours or less in one Temperature equal to or higher than a temperature T1 determined by the formula (1) based on the content of the constituent elements and equal to or lower than 1350 ° C; and an aging heat treatment step in the form of heating the additively manufactured object for 1 to 30 hours at a temperature of 800 ° C to 950 ° C after the heat treatment step to optimize carbide deposition.
