Joining of amorphous metals to crystalline structures is an engineering challenge for future applications of bulk metallic glasses (BMGs). One promising approach is to use power ultrasonics to achieve BMG to Aluminum joints in the solid state. Central objectives of this paper are the feasibility of ultrasonic welding to realize amorphous joints. Therefore different process parameters like welding energy and temperature, related monotonic mechanical properties as well as the interfacial microstructure of the joints was studied by electron microscopy and spectroscopy.
Ultrasonic spot welding was applied to enable direct joints between Zr-based bulk metallic glasses of type AMZ4 (Heraeus, Germany) to automotive aluminum alloys of type AA5754 (Hydro, Germany).
The current findings will be summarized to propose some future applications for ultrasonic welding of BMG to established engineering materials.
