摘 要: 对工业化条件下添加返回炉料生产TA15钛合金加工材进行基础研究。将屑状、块状返回炉料进行净化处理后添加于TA15合金,经熔炼、锻造后制备不同规格棒材(d20~120 mm)。对棒材进行显微组织、力学性能分析,并同未添加返回炉料棒材进行对比以考察添加返回炉料后棒材综合性能。结果表明:添加返回炉料生产的TA15合金棒材完全满足标准要求;除强度略高外,组织、力学性能与未添加返回炉料的棒材基本相当,但需对返回炉料进行净化处理及加工材杂质元素进行控制。

Abstract:Basic research for TA15 titanium alloy working was performed under the conditions of industrialized production with return charge. The dust-like and massive return charge was added for TA15 titanium alloy after cleaning treatment. The bars with different diameters from 20 mm to 120 mm were prepared after melting and forging. The microstructure and mechanical properties of the bar were analyzed, and the comparative test was performed with the bars without return charge in order to study the comprehensive performance of the bars with return charge. The results show that the bars with return charge meet the standard requirements completely. The microstructure and mechanical properties are roughly equal with the bars without return charge except that the strength is slightly higher. But futher study is required for the pure processing of return charge and impurity control of the working material.
