摘要
A Ni-base directionally solidified superalloy or a Ni-base single crystal superalloy, characterized in that it has a composition, in wt %: Al: 5.0 to 7.0 %, Ta+Nb+Ti: 4.0 to 16.0 %, Mo: 1.0 to 4.5 wt %, W: 4.0 to 8.0 wt %, Re: 3.0 to 8.0 wt %, Hf: 2.0 wt % or less, Cr: 10.0 % or less, Co: 15.0 % or les s, Ru: 1.0 to 4.0 wt %, C: 0.2 wt % or less, B: 0.03 %, and balance: Ni and inevitable impurities. The Ni-base base directionally solidified superalloy or single crystal superalloy has an enhanced creep strength at high temperature s, and thus can be used for a turbine blade, a turbine vane and the like of a g as turbine for use in a jet engine or for industrial use.
