DD2单晶合金长期时效后的组织与性能

Microstructure and Endurance Property of DD2 Single Crystal Alloy after Long ageing

研究了DD2单晶合金经850℃、900℃,1000h、2000h和3000h长期时效后显微组织中的γ'相及合金持久性能。结果表明,DD2单晶合金时效后无任何有害相产生。

This paper investigated microstructure and endurance property of DD2 single crystal alloy after ageing at 850℃ , 900℃ for 1000h, 2000h, 3000h. The results showed that TCP phase has not appeared in DD2 single crystal alloy after ageing.
