    摘要:

    通過改變含Re單晶鎳基高溫合金熱處理過程中的一次時(shí)效溫度（1150， 1180 和1200 ℃），獲得了3種不同形貌和尺寸的γ′相。隨后，對(duì)含有不同γ′形貌的3種樣品進(jìn)行了中溫高應(yīng)力（760 ℃/800 MPa）持久試驗(yàn)。結(jié)果表明，γ′相的大小對(duì)單晶高溫合金的持久性能有很大影響。適當(dāng)增大γ′相的尺寸可以促進(jìn)合金的均勻變形，從而提高合金的中溫持久壽命。

    Abstract:

    Three kinds of γ′ phases with different morphologies and sizes were obtained by changing the primary aging temperature (1150, 1180 and 1200 °C) in the heat treatment process. Then, the samples with different γ′ morphologies were tested under condition of intermediate temperature and high stress (760 °C/800 MPa). The results show that the size of γ′ phase plays an important role in the stress rupture property. Increasing the size of γ′ phase appropriately can promote the uniform deformation of the alloy, thus improving the stress rupture life of the alloy.
