The automobile manufacturing industry, until recent years, has been using steel for car body components and the main method joining these always Resistance Spot Welding. However, since global trends toward CO 2 reduction resource efficiency have significantly increased, importance usage of lightweight materials enhanced as well. New such aluminum magnesium alloys, carbon-fiber-reinforced plastics, etc., become a reality, thanks to new fastening technologies. Flow drill screw driving (FDS) is...
Based on several years of research, this paper presents some approaches industrial installation thixoforging steel with an important potential innovative technology. The possibility Thixoforging industrialization makes it possible to consider new components production. From billet final part complex shape obtained in one step, “keys” are developed as heating system, transfer and die design.
Steel thixoforging process combines the advantages of performing parts having highly complex shapes and good mechanical properties. These result from shear thinning flow behaviour semi-solids due to microstructure changes during material deformation. Many parameters such as steel grade, raw speed, slug temperature, tool temperature influence process. In this work, we are interested in analysing thermal conditions well ram speed on final parts. To do so, thixo-extrusion tests a high hydraulic...

Friction Stir Welding (FSW) is an innovative welding process increasingly used by industry for the of aluminum alloys. In order to reduce high investment costs a dedicated FSW’s machine and in offer more flexibility weld complex geometry, payload robots may be used. A serial kinematics robot meets these specifications but under stresses generated during welding, its structure readily deforms. The consequences are deviations tool nominal position with respect seam. work presented here...
The present paper focuses the modelling and simulation of a direct thixoextrusion test achieved on C38 semi-solid steel. Many parameters related to thermal, mechanical, material features are involved but currently unknown. Consequently validate simulation, it is important get various experimental informations during correlate them with simulated results. In previous (Becker et al, 2008), force-displacement curve, temperature within die, macro micro structure obtained for different process...
The presented work is dedicated to studying the forgeability of bimaterial cladded workpiece. Hot upsetting tests cylindrical low carbon steel (C15) billets weld (MIG) by stainless (SS316L) are experimentally and numerically studied. Upsetting with different ratios performed in tribology conditions at 1050°C which within better temperature range both substrate cladding materials[ ]. Slab model finite-element simulation conducted parametrically study potential viscoplastic law adopted...
The high temperature range for steel semi-solid state makes the experiments particularly challenging. While response under shear or compression loadings was studied, few results concerned tensile loading. In this paper, an experimental protocol determined to characterize uniaxial of so-called C38 LTT with a Gleeble simulator. specimen heated by Joule heating effect at around 10°C/s. measured during tests using ultraviolet pyrometer. variation in both ductility and strength material has been...
