    Abstract

    The age-hardening phase in the most common nickel-chromium alloys hardened with aluminum and titanium is based on the ordered compound N13AI, which is usually denoted in phase diagrams as the gamma prime (γ) phase (1). In alloys of this type, it is generally thought that titanium as well as chromium, iron, and perhaps other elements can enter the gamma prime phase substitutionally. This latter circumstance provides an explanation for the fact that the volume of γ precipitate observed in these alloys is far beyond what one would expect if only pure Ni 3Al formed. Recently the importance of grain boundary carbide phases upon properties in these systems has also been recognized (2).
