Cu/Al复合带固-液铸轧复合界面演化(英文)
发布时间:2022-08-23 14:48
利用固-液铸轧复合(简称SLCRB)技术,在d160 mm×150 mm二辊实验铸轧机上制备Cu/Al复合带,并对其界面扩散层的反应程度、反应产物组成及显微组织演变规律进行SEM、EDS和XRD分析。结果表明,铸轧液相熔池内,液态铝液与铜带接触后在其表面形成初始渗铝层,界面成分主要为α(Al)+Cu Al2,且扩散层厚度在高温下逐渐生长变厚,最厚处约为10μm;进入低于kiss点的固相区后,扩散层在剧烈轧制延伸变形作用下破裂,界面两侧原始基材被挤出接触后形成新的复合界面,在铸轧出口处形成沿轧制方向弥散分布的CuAl2、CuAl和Cu9Al4,扩散层平均厚度由10μm减薄至5μm且较为均匀。剥离和折弯性能测试结果表明,所制备的Cu/Al复合带剥离断裂面出现在Al基体侧,断口呈显著韧性断裂,试件经90°~180°折弯后未出现界面撕裂现象。研究成果为高效短流程制备Cu/Al复合带提供了工艺基础。
