Metallurgical Considerations Involved in the Development of Nickel-Base High-Temperature Sheet Alloys

The effects of compositional variations and the influence of production methods and heat-treatment on the properties of titanium and aluminum-hardened nickel-base alloys are described to illustrate metallurgical considerations involved in development of nickel-base high-temperature sheet alloys. Particular attention is drawn to conflicting effects of compositional variations on the property requirements which must be specified for sheet material and to the need for compromise in order to obtain a satisfactory combination of properties.
