The axial force measurement plays important role in tool designing and identification of its restrictions. Also, it is vital in design of machine mechanism and optimization of welding process parameters. In this study, a friction stir welded butt join on AA7075-T651 aluminum alloy plate is investigated. With change of some parameters, factors including axial force, mechanical properties, microh...

introduction spiral conveyors effectively carry solid masses as free or partly free flow of materials. they create good throughput and they are the perfect solution to solve the problems of transport, due to their simple structure, high efficiency and low maintenance costs. this study aims to investigate the performance characteristics of conveyors as function of auger diameter, rotational spee...

Nowadays, the role of light weight materials has grown up in important industries such as aerospace and biomechanics, but before the appliance, their strength should be increased. A modern way to increase this factor along with the lightweight factoris using bimetal sheets, hence, the design of multilayer sheets has been very much considered recently. In this study, explosive welded Cu/St/Cu mu...

Welding speed and rotational speed have been singled out as the most influential welding parameters which affect the tensile strength as well as the hardness in Friction Stir Welding (FSW). It is however problematic to determine the possible welding speed and rotational speed given the Ultimate Tensile Strength (UTS) since there are several combinations of welding speeds and rotational speeds t...

This paper demonstrates two improvements in coding techniques that could be used for memory word coding. First, within the fixed structure of a Hamming single-error-correcting, double-errordetecting (SEC/DED) code, an improvement can be obtained in circuit cost and operational speed over more conventional code implementations. Second, the mechanics of error correction in a fault-tolerant comput...

Friction stir welding is a relatively new solid state joining process, which is suitable for welding similar and dissimilar materials.  The present research work concentrates on the effect of tool rotational speed on the tensile, microstructural properties and microhardness of the friction stir welded joints of different grades of austenitic stainless steel sheets. Four different tool rotationa...
