热处理制度对DD6单晶合金γ′相尺寸和数量影响

Effects of Heat Treatment Regime on the Size and Amount of γ′ Phase of DD6 Single Crystal Superalloy

研究了热处理制度对 DD6单晶合金的 γ′相尺寸和数量的影响。结果表明 :固溶温度对 γ′相的尺寸和数量有影响 ,时效处理使 γ′相的尺寸和数量增加 ,立方化程度改善。与二次时效相比 ,一次时效对 γ′相的影响更大。

WT5BZ]The effects of the heat treatment regime on the size and amount of γ′phase of DD6 Ni based single crystal superalloy have been investigated The research results show that the solution temperature has the effects on the size and amount of γ′phase of DD6 single crystal Aging treatment results in the increasement of the size and amount of γ′ phase of DD6 single crystal, and improvement of regularity of γ′ phase The first aging treatment has more effects on the size and amount of γ′phase of DD6 than the second aging treatment
