An Investigation of the Control Parameters for Aluminum 3003 under Ultrasonic Consolidation
MetadataShow full item record
In this article, we investigate an innovative solid-state welding technique called Ultrasonic Consolidation (UC) that is being developed as a freeform process for the layered fabrication of aluminium tapes. UC involves the use of high frequency, low amplitude mechanical vibrations that induce combined static and oscillating shear forces to produce elastic-plastic deformation at the work-piece interface. This tends to break up and disperse aluminium oxide and permits atomic diffusion to occur. The work centres on material characterisation of aluminium tapes for aerospace and tooling applications. This paper will look at the mechanical properties of aluminum 3003 specimens prepared by UC using different control parameters that will lead to the determination of a general process window.
