NICKEL ALLOYS: THE HEART OF GAS TURBINE ENGINES

Gas turbines create such a provocative high-temperature materials development challenge that metallurgists who work in this field usually consider themselves select and fortunate. Their response to the challenge has resulted in a constant issue of new iron, cobalt, and nickel superalloy compositions; of these, nickel-base super alloys are the most complex, the most widely used for the hottest parts, and to some extent the most fascinating. This paper is an attempt to explain at least some of the mystery of these alloys for the engineers and designers who use their properties, and perhaps present a few unique points of view for metallurgists. However, little attempt will be made to discuss properties in detail; they are a matter of common record. Also, the alloys will be discussed only in a general sense; individual alloys will be used only for examples. Rather, emphasis will be on fundamental principles common to most nickel superalloy systems.
