Single-crystal nickel-based superalloy, more particularly for turbine blades

摘要

A low density superalloy having good resistance to oxidation has the following composition by weight: -Co: 5.0 to 6.0% -W: 4.8 to 5.2% -Cr: 7.8 to 8.3% -Al: 5.8 to 6.1% -Ta: 3.3 to 3.7% -Mo: 2.1 to 2.4% -Ti: 1.8 to 2.2% -B: /=10 ppm -Zr: /=50 ppm -Ni: balance to 100%. -
