    摘要: A Ni-based single crystal superalloy with good resistance to creep deformation and creep life at a high temperature is formed by adjusting the quantity of relatively inexpensive alloy elements while minimizing the quantity of expensive alloy elements. The Ni-based single crystal superalloy with good creep properties comprises Co: 11.5˜13.5%, Cr: 3.0˜5.0%, Mo: 0.7˜2.0%, W: 8.5˜10.5%, Al: 4.5˜6.5%, Ti: 0.5˜2.0%, Ta: 6.0˜8.0%, Re: 2.0˜4.0%, Ru: 0.1˜2.0% in Weight %, with the rest of the superalloy comprising Ni and other inevitable impurities. In addition, the superalloy has a mixed structure of the γ matrix and γ′ particles.
