Abstract:
The International Conference on Extrusion and Benchmark was held for the fourth time. Invited keynote speakers and contributors from academia and industry reported on the latest advances in extrusion technology and its simulation. The contributions covered a wide range of topics and are grouped into the categories of: benchmark, microstructure, seam welds & composite extrusion, material flow & constitutive equations, friction evaluation, dies & tools, and process control & optimization. However, many more topics such as new materials and new profiles have also been covered.The keynote address discusses metallurgical and engineering challenges in magnesium extrusion. The Extrusion Benchmark for 2013 presents the experimental analysis of Mandrel deflection, local temperature, and pressure in extrusion dies. Another 17 papers cover friction evaluation, material flow, seam welding phenomena, microstructure, and processes and process optimization. Among the topics are a new high-speed friction test for extrusion processes, a novel method for three-dimensional die design in the extrusion process using equi-potential lines, simulating material flow coupled with die analysis in complex-shape extrusion, the non-destructive detection of weld seams in extruded aluminum profiles, and manufacturing steel-reinforced aluminum parts by co-extrusion and subsequent forging.
