Abstract

本发明涉及冶金技术领域，具体为一种基于薄带铸轧的原位Y2O3改性TA1薄带的制备方法。按以下步骤进行：（1）按设定成分冶炼合金熔体；（2）在水平铸辊前后装入等静压石墨侧封板；（3）将真空腔室抽真空通入氩气；（4）采用悬浮感应熔炼技术进行分次投料与熔炼；（5）在水平铸辊的辊面采用喷枪向辊面喷射氦气；（6）将悬浮感应熔炼坩埚内的熔体倾翻至中间包内；（7）熔体经中间包水口流入水平铸辊中间；（8）熔体经水平铸辊急速冷却后，快速凝固形成厚度为1.0~3.0 mm的薄带。本发明采用薄带铸轧直接制备出原位Y2O3改性的TA1薄带，可避免Y2O3的团聚，为TA1薄带的短流程制备提供了一种新的技术路径。
