Ultrasonic additive manufacturing (UAM) technology can produce structural materials with complex geometries and embedded sensors. Under UAM-processing conditions, interfaces are created between these due to high-strain rate (> 105 s−1) plastic deformation. Fundamental understanding of strengthening mechanisms at needed for engineering deployment. In this research, we correlated the interface mi...

In this research the interface structure of dissimilar joint between AISI 4130 and AISI316L steels produced by GTAW process was evaluated. ERNiCr-3 was used as a filler metal for this joint. After welding the microstructure of different areas including weld metals, heat affected zones and interfaces were studied by optical microscope (OM), scanning electron microscope (SEM) and energy dispersiv...

FSW material flow and phase transformation were studied at the interface of dissimilar welding of Al 6013 to Mg. Defect free butt weld was obtained when aluminum and magnesium test plates were placed in the advancing side and retreating side respectively, and the tool was placed 1 mm off the weld centerline into the aluminum side. In order to understand how the materials flow during FSW, steel ...

Dissimilar metal joining between Al and Cu is effective for reducing the weight cost of electrical components. In this study, dissimilar lap pure to with an Al-Ni filler material was conducted using tungsten inert gas (TIG) arc brazing, effect Ni on joint strength associated microstructure intermetallic compound (IMC) layer at interface examined. The addition effectively increased interfacial j...
