In the present investigation, numerical code WELDSIM is used to simulate butt welding of 4 mm thick plates S355 steel and AA6082-T6 by Hybrid Metal Extrusion Bonding (HYB). This a new solid state joining process using continuous extrusion as technique enable aluminium filler metal additions. WELDSIM, finite element heat flow model coupled frictional heating model, an isokinetic diffusion for in...

We propose an experimental method for investigating the kinematics of metal flow in twist extrusion (TE). The method is based on a theoretical model of the velocity field. The parameters of this model are determined to satisfy the observed flow-line for characteristic points of the specimen. The model incorporates two physical constraints: (1) metal flow is limited by the surface of the die; (2...

One of the most important applications of carbon nanotubes (CNTs) is as reinforcement of metal matrix composites, because of their excellent mechanical properties. In this study, Al-TiO2-multi walled carbon nanotubes (MWCNTs) nanocomposite is fabricated using isostatic pressing followed by hot extrusion. Mechanical alloying is used to mix powders of aluminium, TiO2 and MWCNTs. TiO2 with the amo...

one of the most important parts of power transmission in automotives is c.v. joint, which consists of four components where exterior bowl is one of them. due to its complexity, and importance in automobile and existence of high stresses, forging process is the only cost effective method of production. hence, the best method of production of this part is forging process. the exterior part of c.v...

Abstract Magnesium (Mg) alloys are the lightest metal structural material for engineering applications and therefore have a wide market of applications. However, compared to steel aluminum alloys, Mg lower mechanical properties, which greatly limits their application. Extrusion is one most important processing methods its alloys. effect such heterogeneous microstructure achieved at low temperat...

Abstract Reactive extrusion printing (REP) is demonstrated as an approach to simultaneously crystallize and deposit films of the metal–organic framework (MOF) Cu 3 btc 2 (btc=1,3,5‐benzenetricarboxylate), also known HKUST‐1. The technique co‐delivers inks copper(II) acetate H starting materials directly on‐surface on‐location for rapid nucleation into at room temperature. were analyzed using PX...

In this study, five microcrystalline cellulose (MCC) grades were physically characterized and their extrusion-spheronization behaviours were characterized in terms of water requirements and pellet shape profiles. It was found that the MCC grades differed significantly in the physical properties investigated. Physical properties of MCC were found to influence the water requirement for extrusion-...
