从头开始的高通量工作正在不断地在各种合金系统中识别出新的金属间化合物,这些化合物以前被认为是具有良好特征的。虽然此类预测可能在绝对零附近有效,但它们存在此类相在与典型合成条件相关的较高温度下变得不稳定的风险。我们说明了如何通过将 Calphad 建模集成到高通量循环中来快速测试这种可能性。作为一个例子,我们研究了 Ni-Re 体系,其中 D019 和 D1a 相被预测为可能的金属间化合物。我们确认这些相在实际合成温度下确实稳定,并解释了它们在之前的评估中如何被忽视。
Ab initio high-throughput efforts are continuously identifying new intermetallic compounds in a wide range of alloy systems that were previously thought to be well-characterized. While such predictions are likely valid near absolute zero, they carry the risk that such phases become unstable at the higher temperature relevant to typical synthesis conditions. We illustrate how this possibility can be rapidly tested by integrating Calphad modeling into the high-throughput loop. As an example, we investigate the Ni-Re system, in which D019and D1aphases were predicted as possible intermetallic compounds. We confirm that these phases are indeed stable at practical synthesis temperatures and explain how they could have been overlooked in prior assessments.
