A single-crystal superalloy with improved creep-rupture strength has been announced by Cannon-Muskegon Corp., Muskegon, Mich. Designated CMSX-486, the alloy is grain-boundary strengthened through optimized additions of boron, carbon, hafnium, and zirconium. It is designed for service as-cast, to maximize complex casting yield without solution heat treatment recrystallization problems.

The nickel-base superalloy contains 9.3% cobalt, 8.6% tungsten, 5.7% aluminum, 5% chromium, and 3% rhenium. The improved performance of single-crystal superalloy components is a result of superior ...
