摘要
进行T2铜弹带与50#钢弹体磁脉冲焊接实验研究。结果表明:获得的冶金连接接头呈波状界面,波长和幅值分别约为60、30μm,没有泛铁现象发生;接头的轴向和环向压剪强度为91 MPa和132.37 MPa,显著高于铜环母材的初始屈服强度;接头扭转和密封性测试破坏均发生在较弱母材——T2铜环,对应最大承载能力分别为84.36 N·m和18 MPa。
Experiments on magnetic pulse welding of T2 copper rotating band to 50#carbon steel tube were carried out. The metallurgical joint between them shows the wavy bonding mode,where the wavelength and amplitude are 60 μm and 30 μm,respectively. Almost no iron element diffuses into copper. The axial and loop shear strength of the welded joint are 91 MPa and132.37 MPa,which are much higher than the initial yield strength of copper. The torsion instability and bulging crack occur in copper and the corresponding maxium loading capacities are 84.36 N·m and 18 MPa,respectively.
