Effect of Long-Term Aging on Microstructure and Medium Temperature Performance of Single Crystal Superalloy DD407

Abstract
Microstructure and its effect on medium temperature performance of single crystal superalloy DD407 was investigated after long-term aging without stress at 900℃ for 3000h.The results show that the microstructure of DD407 is stable and no detrimental phase precipitated.Tensile strength reminds steady and ductility increases at 760℃ after long-term...
