    摘要:

    采用正交實(shí)驗(yàn)設(shè)計(jì)方法，探討了Co，W和Ti及其含量對(duì)鎳基單晶高溫合金持久性能的影響，通過(guò)數(shù)學(xué)分析，對(duì)合金成分進(jìn)行了優(yōu)化。結(jié)果表明：此合金系中Ti含量對(duì)持久壽命影響最大，Co次之，W對(duì)持久壽命影響最??；當(dāng)Co，W和Ti含量（ω，％）分別為10，8和0時(shí)合金具有較好的持久性能。此合金長(zhǎng)期時(shí)效后還顯示出良好的組織穩(wěn)定性。

    Abstract:

    The influence of Cobalt, Tungsten, and Titanium on stress-rupture properties of Nickel-base single crystal superalloy has been investigated using orthogonal arrays experimental design. The compositions of alloy have been optimized by mathematical analysis. The results show that Ti content has the most important influence on persistent lives and it is followed by Co, W in the effects. The persistent life is long when the alloy contains 10wt%Co, 8wt%W and 0wt%Ti. This alloy also has high microstructure stability after long-term ageing.
