Alternative methods for dissimilar metal joining particularly aluminium and copper have gain interest in manufacturing sectors. Friction stir spot welding was carried out on the AA6061 C11000 wires of 2 mm diameter. This research paper reported results microstructures mechanical properties spot-welded joints, also special attention is provided electrical resistivity welds. The reveal informatio...

Introduction The lowest known portion of the Poorman Formation as determined from diamond drilling and mapping is the Yates Unit. It largely comprises amphibolite, but also contains interbedded volcaniclastics, calc-silicate beds, metachert, and carbonate-rich semipelitic rocks. This unit is exposed at the surface in the Blacktail Gulch area north of Lead and continues down-plunge to the southe...

Here we describe a bench-top cryostat system to control the temperature of liquid ethane in a cryo-plunge apparatus designed for biological specimen preparation for electron cryomicroscopy. It comprises a foam insulated Dewar containing a copper cryostat cup, whose temperature is controlled via an active feedback system to within 0.1 K. The device can easily be incorporated into existing manual...

This paper describes series of studies concerned with welding Sc-modified AA2519 at the Military University Technology. The modification alloy contains a higher concentration scandium and zirconium it has been developed in Institute Non Ferrous Metals, Light Metals Division Skawina. examination involves friction stir (FSW) laser beam (LBW) 5 mm thick AA2519-T62 extrusion. FSW process parameters...
