Two laboratory heats of Waspaloy were melted with carbon contents of 0.01 and 0.10%. The properties and chemical gradients were measured. Tensile ductility as-cast and heat treated of the 0.01% carbon heat was markedly superior. Segregation of titanium and molybdenum was shown to exist but the higher carbon alloy formed copious amounts of (Ti, Mo)C and reduced the matrix enrichment of these elements. Due to the lack of MC formation, the higher titanium content of the matrix in the low carbon heat led to the formation of unusual structures that were studied by microprobe analysis and metallography.
