摘要： The present invention suggests a method of heat treatment of a Ni-based superalloy that improves resistance against creep, fatigue and stress corrosion cracking while being economical and easy, and a Ni-based superalloy produced by using the same. The method and the superalloy of the present invention include solution treatment at the high temperature region during a heat treatment process after manufacturing or final cold working fabrication. Immediately following the solution treatment, the material is slowly cooled at 1˜15° C./minute down to the intermediate temperature region for aging treatment. After the slow cooling stage, aging treatment is directly performed by holding it at the intermediate temperature region for the prescribed time. Lastly, the aging treatment is followed by air-cooling stage.

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.
