摘要
研究了Nimonic C263合金在不同温度和应力条件下的恒载荷蠕变行为。结果表明,合金蠕变曲线在很短减速蠕变阶段后,既可表现出稳态蠕变阶段,最小蠕变速率,也可表现出加速蠕变阶段,取决于组织的不同变化。讨论了合金的蠕变变形与断裂机制。
The creep behavior of a nickel-base superalloy Nimonic C263 had been studied at constant load and temperature in the 35-480 MPa and 700-9000 C. The results have shown a very strong dependence of the creep curve shape with the applied stress and temperature, due to the microstructure change. The creep deformation and fracture mechanisms have also been discussed.
