Friction welding of Zr,1Ti14Cu12.5Ni10Be22.5 bulk metallic glass and temperature field simulation
In order to enhance the application of bulk metallic glass (BMG) as engineer material,it is necessary to develop appropriate bonding technology to solve the problems of size limitation and weldability.In this work,a friction welding set-up was constructed,and the Zr41Ti14Cu12.sNi10Be22.5BMG rods were joined.The joint interface zone was examined by X-ray diffraction,Scanning electron microscope,Vickers Micro-hardness and Transmission electron microscope.The results showed that the BMG rods were successfully joined,where no crystallization and visible defects were observed.The welding joint maintained the amorphous structure except few nanocrystallines occurred.Then the temperature field simulation was executed using ANSYS finite element software to optimize the welding parameters.It indicated that friction time cannot exceed 0.25s under the given experiment conditions,otherwise the crystallization would occurred,which is in good agrcemcnt with the experiment.It is concluded that the temperature field simulation can be used to guide the experiment and the friction welding can be used to join the BMG.
