Inconel 718是一种在过去几十年中广泛应用于航空发动机的镍基高温合金,其高温强度来源于三种垂直变体的盘状γ双素数(γ″)以及较少的球形γ素数(γ′)沉淀。在目前的工作中,我们在直接时效冷轧Inconel 718中观察到一种具有定制取向和形状的异常γ″变体,蠕变试验证明其在650 °C时的抗蠕变性能优于通常垂直的γ″变体。研究结果可为718型高温合金中γ″相强化效果最大化的工艺优化和二次粒子配置设计提供新的思路。
Inconel 718 is a widely used nickel-based superalloy in aircraft engines during the past decades, whose elevated temperature strength derives from disc-shaped gamma double prime (γ″) in three perpendicular variants plus less spherical gamma prime (γ′) precipitates. In present work, we observed an abnormal γ″ variant with tailored orientation and shape in directly aged cold-rolled Inconel 718, creep tests proved its substantial benefits in improving creep resistance at 650 °C superior to commonly perpendicular γ″ variants. The results can provide new insights for processing optimization and second-particle configuration design to maximize the strengthening effect of γ″ phase in 718-type superalloys.
