This study investigated the migration patterns of oxygen in the deoxidation process of Ti-48Al alloy scrap using electromagnetic levitation (EML) technology. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) were employed to analyze the oxygen distribution patterns and migration path during EML. The refining process resulted in three types of oxygen migration: (1) escape from the lattice and evaporation in the form of AlO, AlO; (2) formation of metal oxides and remaining in the alloy melt; (3) attachment to the quartz tube wall in the form of metal oxides such as AlO and CrO. The oxygen content of the scrap was dropped with a deoxidation ratio of 62%. It indicated that EML can greatly promote the migration and removal of oxygen elements in Ti-Al alloy scrap.
本研究利用电磁悬浮(EML)技术研究了Ti-48Al合金废料脱氧过程中氧的迁移模式。采用扫描电子显微镜(SEM)、X射线衍射(XRD)和X射线光电子能谱(XPS)分析了电磁悬浮过程中氧的分布模式和迁移路径。精炼过程导致了三种类型的氧迁移:(1)从晶格中逸出并以AlO、AlO的形式蒸发;(2)形成金属氧化物并残留在合金熔体中;(3)以AlO和CrO等金属氧化物的形式附着在石英管壁上。废料的氧含量下降,脱氧率为62%。这表明电磁悬浮可以极大地促进Ti-Al合金废料中氧元素的迁移和去除。
