The patent agency is Beijing Chaofan Hongyu Intellectual Property Agency Co., Ltd., with patent agent Shi Chao. The classification codes are C22C19/05, C22C1/02, C22C1/06, C22F1/10, B22D27/04, B22D27/20, C30B29/52, C30B11/00, C30B33/02.

Patent Abstract: The present invention relates to the technical field of high-temperature alloys, specifically a nickel-based single crystal high-temperature alloy and its preparation method and application. The alloy comprises the following weight percentages of chemical components: Cr 3%–4%, Mo 0.5%–0.8%, W 5%–6.5%, Al 5%–6%, Ti 0.7%–1%, Re 4%–5%, Co 9%–11%, Ta 7.5%–9%, Hf 0.078%–0.15%, with the remainder being Ni. Through the coordinated matching of these components, the alloy exhibits excellent high-temperature strength, significantly reduces costs, improves long-term organizational stability, and has low TCP (topologically close-packed) phase precipitation tendency.

Beijing Steel Research High Nan Technology Co., Ltd. was established on November 8, 2002, and listed on the Shenzhen Stock Exchange on December 25, 2009.
