Abstract
A Ni—Fe based super alloy having high strength and toughness at high temperatures even when used in high-temperature environments, and a process of producing the super alloy. A turbine disk using the super alloy, a process of producing the turbine disk, a turbine spacer using the super alloy, and a process of producing the turbine spacer, as well as a gas turbine are also provided. The Ni—Fe based super alloy contains not more than 0.03% by weight of C, 14-18% of Cr, 15-45% of Fe, 0.5-2.0% of Al, not more than 0.05% of N, 0.5 to 2.0% of Ti, 1.5-5.0% of Nb, and Ni as a main ingredient.
