Abstract (en)
[origin: WO03040419A1] The invention relates to a method for developing a nickel-base super alloy, consisting of a gamma phase and a gamma ' phase, for the production of monocrystalline or specifically solidified substance bodies. The invention is characterized in that the properties of nickel-base super alloys, exhibiting a volume proportion of at least 50 %, are optimized after degradation at room temperature, by selecting the composition of the alloy in such a way that a high as possible positive lattice dislocation (delta) is obtained at room temperature between the gamma phase and the gamma ' phase. As a result the apparent limit of elasticity at room temperature after degradation is relatively high and only a small difference of apparent limits of elasticity occurs between the initial state and a degraded state.
