Ni basic unidirectional solidification super alloy and Ni basic monocrystal super alloy

摘要

Al: 5.0 - 7.0wt%, Ta+Nb+Ti: 4.0 - 16.0wt%, Mo: 1.0 - 4.5wt%, W: 4.0 - 8.0wt%, Re: 3.0 - 8.0wt%, Hf: Below 2.0wt%, Cr: Below 10.0wt%, Co: Below 15.0wt%, Ru: 1.0 - 4.0wt%, C: Below 0.2wt%, B: It contains below 0.03wt%, the remainder Ni is something which possesses the constitution which consists of the inevitable impurity, enabled, it makes the Ni basic unidirectional solidification super alloy or the Ni basic monocrystal super alloy whose creeping strength at high temperature is large in turbine blade and the turbine vane such as jet engine and gas turbine etc for industry.
