Abstract

The alloy has the compn. (wt%) 0.04-0.08C, 13-16Cr, 2.3-3.0Ti, 1.8-3.0Al, 2.2-6.0Nb, 6-12Co, 4-8Mo, 0.001-0.1La, 0.101-0.01B, 0.001-0.03Ce, balance Ni. The alloy is composed of a solid soln. of the main alloying elements Al, Ti, Nb which are present in greater quantities than in known heat-resisting ni alloys, and which produce a high fatigue strength and good ductility. The thermal stability is increased by higher contents of Mo and Nb. La and Ce give a grain refinement.
