ABSTRACT:
Heat-resistant alloy containing specially controlled proportions of nickel, chromium, titanium, aluminum, tungsten, molybdenum and tantalum is especially advantageous for production of heat resistant castings having strength and ductility throughout a broad range of temperatures, particularly including stress-rupture strength at 1850.degree.F. and ductility at intermediate temperatures such as 1400.degree.F.
