Print version record.

This special volume covers all aspects of extrusion in the world of today: from innovative tools for die design to a deep analysis of the extrusion defects that still afflict most extruders and users around the world. The papers are grouped into the categories of: benchmarking, process optimization and innovation, material flow and friction, dies and tooling, seam welds and microstructures. It is expected that this book will become a source of invaluable information which will aid the everyday work of scientific and industrial researchers, engineers and students. Review from Book News Inc.: Drawn from papers presented at the 2011 International Conference on Extrusion and Benchmark, this collection of thirty-three articles on industrial technologies showcases current scholarship in materials extrusion techniques and simulation for materials testing. The work is divided into sections covering extrusion benchmarks, process optimization, innovative processes, material flow and friction evaluation, seam welding, dies and tools and microstructure prediction modeling. Individual entries include abstracts, illustrations, and notes, and a volume-wide key word and author index is provided. Contributors are academics in material engineering form European and Asian institutions.
