| 摘 要： | 设计了一种非晶合金摩擦焊装置,以Zr41Ti14Cu12.5Ni10Be22.5非晶棒料为研究对象,进行了摩擦焊试验.焊接样品经SEM,XRD,维氏硬度、TEM等检测,结果显示焊接界面无明显未熔合,样品仍然保持非晶态,接头硬度总体增大,接头处出现了纳米晶.采用ANSYS软件对非晶合金摩擦焊的温度场进行仿真.结果表明,在摩擦时间t=0.25s时摩擦界面中心温度超过非晶棒料玻璃转变温度,接触面全部进入过冷液相区,应进行顶锻.仿真结果与摩擦焊试验结果基本吻合,有利于指导焊接试验.

| Abstract: | A new friction welding system was developed to join the bulk metallic glass.The Zr41 Ti14 Cu12.5 Ni10 Be22.5 bulk metallic glass bars were joined by this welding system.The welded sample was tested by scanning electron microscope,X-ray diffraction,Vickers hardness and transmission electron microscope.The results show that no incomplete fusion or obvious defects are found,and the welded joint maintains the amorphous structure.The hardness is enhanced because a few nanocrystallines occur in the joint.Subsequently,the friction welding temperature field was simulated using finite element software ANSYS.The simulation results indicate that the friction time can not exceed 0.25 s and the upset forging should be carried out.The temperature on center interface exceeds the glass transition temperature of Zr41Ti14Cu12.5Ni10Be22.5,and the superplastic deformation occurs.It is concluded that the new friction welding system can be used to join the bulk metallic glass bars.The simulation results of temperature field accords well with that of the experiment,which is beneficial to optimize the welding parameters and guide the experiment. |
