A team approach utilizing simultaneous engineering has been used to develop CMSX-4 turbine airfoil components. CMSX-4 is a nickel-base single crystal superalloy containing 3% (wt) rhenium and a high 71% volume fraction of coherent {gamma}{prime} precipitate strengthening phase. The high level of balanced properties determined by extensive laboratory evaluation has been confirmed during engine testing the Allison AE 2100 and AE 301X engines, with the post-test condition of the components, including advanced Castcool{trademark} vane segments, being excellent. Also uncooled vane segments in CMSX-4 have exceeded engineering expectations.
