对铁基高温合金 GH10 9的长期时效作了研究 .结果表明 :强化相 r′的点阵常与 TCP-L aves相含量负相关 ;r′的含量与其尺寸正相关 ,这对合金机械性能有不利的影响 .
The results show that the lattice of the reinforcing phase r ’is often negatively correlated with the content of TCP-L aves, and the content of r’ is positively correlated with the size of the alloy, which has some negative effects on the mechanical properties of the alloy negative effect .
