A team approach involving several turbine engine companies using the concepts of simultaneous engineering has been used to successfully develop (CMSX-4) alloy for turbine blade applications. CMSX-4 alloy is a second-generation, single-crystal cast nickel-base superalloy containing 3% Re and approximately 70% volume fraction of [gamma][prime]. The high level of balanced properties determined by laboratory evaluation has been confirmed during field testing of the Solar Mars T-14000 industrial gas turbine with CMSX-4 single-crystal (SX) blades in both the coated and bare condition. A similar collaborative approach has resulted in the successful development of CM 186 LC alloy for complex, directionally solidified (DS) columnar grain vane segments. CM 186 LC alloy is a second-generation DS columnar grain cast nickel-base superalloy containing 3% Re and approximately 65% volume fraction of [gamma][prime]. Excellent component producibility and quality is demonstrated. Turbine engine testing is scheduled to commence by the end of 1993.
