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. <mtable columnalign="left"><mtr><mtd><mtext> T1 </mtext><mrow><mo> ( </mo><mrow><mo> ° </mo><mtext> C </mtext></mrow><mo> ) </mo></mrow><mo> = </mo><mn> 177 </mn><mo> × </mo><mtext> Ni </mtext><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> + </mo><mn> 176 </mn><mo> × </mo><mtext> Co </mtext><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> + </mo><mn> 172 </mn><mo> × </mo><mtext> Cr </mtext><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> + </mo><mn> 178 </mn><mo> × </mo><mtext> Mo </mtext></mtd></mtr><mtr><mtd><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> + </mo><mn> 174 </mn><mo> × </mo><mtext> W </mtext><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> + </mo><mn> 171 </mn><mo> × </mo><mtext> A1 </mtext><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> + </mo><mn> 170 </mn><mo> × </mo><mtext> Ti </mtext><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> + </mo><mn> 168 </mn><mo> × </mo><mtext> Ta </mtext><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> + </mo></mtd></mtr><mtr><mtd><mn> 163 </mn><mo> × </mo><mtext> Nb </mtext><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> + </mo><mn> 307 </mn><mo> × </mo><mtext> C </mtext><mrow><mo> ( </mo><mtext> % </mtext><mo> ) </mo></mrow><mo> - </mo><mn> 16259 </mn></mtd></mtr></mtable>
