Improvement for creep strength of a second-generation single crystal superalloy by design of heat treatments

Rare Metals 2024年第1期43卷 342-350页

作者： Wan-Shun Xia Xin-Bao Zhao jia-Chen Xu Quan-Zhao Yue Qing-Qing Ding Huan-Chang Duan Yue-Feng Gu hong-Bin Bei Ze Zhang Institute of Superalloys Science and Technology School of Materials Science and EngineeringZhejiang UniversityHangzhou 310027China State Key Laboratory of Silicon and Advanced Materials School of Materials Science and EngineeringZhejiang UniversityHangzhou 310027China

Design of heat treatments is related to the key technology for development of nickel-based single crystal superalloys(Ni-SXs). Based on the full understanding of the solidification characteristics, this work applies optimization design of heat treatments for a second-generation Ni-SX. Microstructure evolution and creep properties are compared in the material under conventional/standard(Std.) and optimized(Opt.) treatments. For the Std. sample,strong dendritic segregations determine inconsistent microstructure evolution in the dendritic(D) and interdendritic region(ID), while the latter serves as weak area to have the prior microcrack initiation, damaging overall performance of the alloy. The Opt. treatment applies higher homogenization temperature, leading to overall reduced segregations, while not inducing incipient melting. A lower temperature of first-step ageing is used to lower the size ofγ'particles. These help to form the more uniform microstructure in dendritic and interdendritic region and relieve the inconsistent microstructure evolution. The balanced local strength makes ID no longer as the weak area,thus restricting microcrack initiation. Great improvement of high temperature and low stress property is obtained by this progress, leading to the pronounced increase of creep rupture life under 1100 °C/140 MPa.

隔水导管定向打桩可有效解决海上加密调整井浅层防碰问题,但目前隔水导管定向打桩缺乏理论模型,作业存在安全风险。根据钻井设计及现场作业需求,首先通过导管鞋受力分析和历史作业数据反演,构建和优化了隔水导管定向打桩井斜角、偏移距离理论模型,然后通过导管与地层的承载力分析,构建了隔水导管定向打桩入泥深度设计模型。研究表明:导管鞋坡口角度是影响定向打桩效果的关键因素,坡口角度合理范围为20°~45°,具体角度需要根据井场地质条件和导管参数进行计算。构建的理论模型在南海东部海上隔水导管定向打桩作业中进行了应用,成功规避了加密调整井浅层碰撞风险,保证了海上作业安全。本研究成果可为海上加密调整井隔水导管定向打桩作业提供理论支撑。
