转速对铝铜层状复合板搅拌摩擦焊接接头组织性能的影响
Journal of Aeronautical Materials（2017）
Abstract
采用搅拌摩擦焊接(FSW)对铝铜层状复合板进行焊接,研究转速对焊接接头组织性能的影响.结果表明:FSW接头在焊缝区域内铝铜金属呈层状分布;随着搅拌头转速的增大,焊核区(NZ)中铝与铜晶粒尺寸增大;转速为1180 r/min时,铝层焊缝中心区域平均显微硬度为33.0 HV,超过母材显微硬度,抗拉强度为127.21 MPa;转速为750 r/min时,铜层焊缝中心区域平均显微硬度为99.7 HV,达到母材显微硬度的82.05%;孔洞缺陷是造成接头力学性能较低的主要原因.
