Intergranular creep resistance affected by grain boundary carbides to suppress lamellae γʹ precipitation in a specially designed inconel 740H variant

Intergranular creep resistance affected by grain boundary carbides to suppress lamellae γʹ precipitation in a specially designed inconel 740H variant

The effects of heat treatment on the microstructure and creep properties of a modified variant of Inconel 740H alloy were studied. This variant was tuned to have a refined composition, reducing C, Cr, and Co contents while increasing the Ti/Al ratio and Mo content to enhance creep resistance. Two he...
