Creep constitutive model of Ni3Al-based single crystal superalloy

摘要

摘要: 结合Ni3Al基单晶高温合金蠕变行为的细观机理，在晶体滑移理论的基础上，建立了描述Ni3Al基单晶高温合金蠕变行为的本构模型，并通过ANSYS提供的UPFs二次开发平台对所建立的本构模型进行了有限元实现。利用蠕变试验数据，结合遗传算法获取了两种Ni3Al基材料的蠕变本构模型参数。利用所建立的蠕变本构模型对两种Ni3Al基材料的高温拉伸试件进行了有限元模拟，与试验结果吻合良好。这表明在晶体滑移理论基础上建立的本构模型是合理的，并且能够较好地描述Ni3Al基单晶高温合金三个阶段的蠕变行为，具有一定的应用价值。

Abstract: Combined with the microscopic mechanism of the creep behavior of Ni3Al-based single crystal superalloy, the creep constitutive model based on the crystal slip theory was established to describe the creep behavior of Ni3Al-based single crystal superalloy. And the finite element implementation of the constitutive model established was conducted through the UPFs redevelopment platform provided by ANSYS. Using the creep test data, the model parameters of two kinds of Ni3Al-based materials were obtained based on genetic algorithm. Using the creep constitutive model established, the finite element simulation of high temperature tensile specimens of two kinds of Ni3Al-based materials was carried out, and the results had a good agreement with the test results. It shows that the creep constitutive model based on the crystal slip theory is reasonable and it can simulate three stages of creep behavior of Ni3Al-based single crystal superalloy well. Therefore, it has a definite application value.
