Abstract
The present inventions offer a nickel-based single crystal alloy which has a high strength, is easy in conducting the solution heat treatment, hardly gives a harmful phase and is resistant to corrosion at high temperature. A nickel-based single crystal alloy is offered where the composition consists of 7-15 of Co, 0.1-4 of Cr, 1-4 of Mo, 4-7 of W, 5.5-6.5 of Al, 5-7 of Ta, 4-5.5 of Re, 0-0.5 each of Hf and V, and 0-2 each of Ti and Nb in terms of % by weight and residual part substantially consists of Ni wherein said alloy may contain unavoidable impurities.
