SINGLE CRYSTAL NICKEL-BASE MATRIX ALLOY |
| 摘要 |
A monocrystalline alloy with a high resistance to creep having a nickel base matrix, with a density of the order of 8.5 and having a percentage, by weight, composition as follows: Co 5 to 8%-Cr 6.5 to 10%-Mo 0.5 to 2.5%-W 5 to 9%-Ta 6 to 9%-Al 4.5 to 5.8%-Ti 1 to 2%-Nb 0 to 1.5%-C, Zr, and B each less than 100 ppm-Ni remainder to 100%. Furthermore, the summation Ta+Mo+1/2 W lies between 11.5% and 13.5% by weight, the atomic sum Ti+Al+Ta+Nb lies between 15.5% and 17%, the atomic sum Ta+Nb+Mo+1/2 W lies between 4% and 5.5%, the atomic sum Ti+Al+Ta+Nb+Mo+1/2 W lies between 17.5% and 19% and the atomic sum Ti+Al lies between 12.8% and 14.5%. |
