Abstract Scope |
Throughout the aerospace and industrial gas turbine industry, computer-aided design, process modelling and ICME are synonymous with leading edge technology development methods. However, there remains value and benefit from the alternate, more traditional evolutionary design methodology where new alloys are developed based upon prior experience with existing alloys and lessons learned. Cannon-Muskegon Corporation has used this evolutionary method to develop and introduce CMSX-4® Plus (SLS) alloy, an improved 3rd generation, single crystal alloy based upon over 30 years of SX alloy development and commercial experience. It is useful and enlightening to review this development history, as it directly reflects upon the resultant alloy and explains the remarkable speed with which CMSX-4 Plus (SLS) alloy was developed and brought to market: 14 months from concept to patent application and first production heat. OEM engine certification, including development of a compatible coating/bond coat, was obtained approximately 6.5 years from start of development. |
