Abstract Scope |
Bulk metallic glasses (BMGs) are very attractive to a range of microelectronic applications including sensing elements, precision optics and micro-geared motors due to its high strength, elasticity, corrosion resistance and soft magnetic properties. However, joining BMGs to dissimilar materials to manufacture interconnects for microelectronic devices is a great challenge. Micro friction stir spot welding (µFSSW) is a novel solid-state joining process which makes it a strong candidate for joining BMGs or BMGs to other crystalline materials to fabricate various types of interconnects. But studies on the dissimilar µFSSW of BMGs to Al alloys are limited. In this paper, experimental investigations are conducted on µFSSW of Zr-based BMGs, i.e, LM105 to 6061 Al alloys. The effect of µFSSW conditions on the weld zone intermetallics formation is studied in relation to the processing force, torque and temperature. |
