As nickel-based superalloys have been widely used in turbine blades of turbo-chargers in automobile industries, this article has presented the creep behavior of the Inconel-713C nickel-based superalloy. For this objective, forced-controlled creep testing has been performed at the temperature of 850 °C and under the stress of 585.5 MPa. Then, the effect of the solutioning process on creep (time-dependent) properties of the superalloy was investigated. Optical and scanning electron microscopies were utilized to study the material microstructure, before and after creep testing. The X-ray diffraction (XRD) spectrometry was also used to detect different phases in the superalloy. Results showed that solutioning at 1200 °C for 1 h had a lowering effect on the creep rupture time of the Inconel-713C superalloy, as the mean size of the γ′ particles crystallite was about 6.8 nm. When the superalloy was aged for 16 h at 930 °C, an insignificant effect with respect to the as-cast sample could be observed, due to the precipitation of NbC carbides (at grain boundaries) and the coarsening behavior of γ′ particles. Consequently, different microstructures led to different creep fracture mechanisms for this alloy. The decomposition of MC carbides to M₂₃C₆ was also observed for all samples after creep testing.

由于镍基高温合金已广泛用于汽车行业的涡轮增压器的涡轮叶片中，因此本文介绍了Inconel-713C镍基高温合金的蠕变行为。为了这个目标，已经在850°C的温度和585.5 MPa的压力下进行了强制控制的蠕变测试。然后，研究了固溶过程对高温合金蠕变（时间相关）性能的影响。在蠕变测试之前和之后，利用光学和扫描电子显微镜来研究材料的微观结构。X射线衍射（XRD）光谱仪还用于检测超合金中的不同相。结果表明，在1200°C下固溶1 h对Inconel-713C高温合金的蠕变断裂时间有降低的影响，γ'粒子的平均粒径为6.8nm左右。当高温合金在930°C下老化16 h时，由于NbC碳化物的沉淀（在晶界处）和γ'颗粒的粗化行为，对铸态样品的影响微不足道。因此，不同的微观结构导致该合金的蠕变断裂机理不同。MC碳化物分解为M蠕变测试后，所有样品均观察到₂₃ C ₆。
