摘要

金属体系的液体和自身固体之间的润湿性是有限的。在本研究中，我们提出了一种基于粉末床熔合成形表面形貌的液态合金与固态合金界面性能评价方法。在电子束增材制造样品的基础上，测量了Ti-6mass%Al-4mass%V的液固接触角，并用Young’s方程计算了其界面张力。Ti-6mass%Al-4mass%V液态合金与固体合金的接触角和界面张力分别为12°和376 mN/m。

Evaluation of liquid/solid interfacial property for Ti-6mass%Al-4mass%V alloy using electron-beam additive manufacturing

wettability between a liquid and its own solid for metal systems is limited. In this study, we propose the evaluation method for the interfacial properties between liquid alloy and its solid alloy based on the morphology of as built surface in powder bed fusion. The liquid/solid contact angle for Ti-6mass%Al-4mass%V is measured based on the sample built by electron-beam additive manufacturing, and its interfacial tension is evaluated by Young ʼ s equa-tion. The contact angle and interfacial tension between Ti-6mass%Al-4mass%V liquid alloy and its solid alloy are found to be 12 °and 376 mN/m, respectively.
