Ultrasonic Extrusion

On June 21 a symposium was sponsored by the Bureau of Naval Weapons on the application of ultrasonic energy in the deformation of metals. At this session, a number of investigators actively working in the field reported informally on the results of their research. The reports revealed that the results achieved by incorporating ultrasonic transducers into conventional metalforming and-cutting operations are sufficiently promising that the technique merits further attention. Data are available to indicate that application of ultrasonic vibrations during metal working can increase speeds, lower forces, and improve surface finishes. All of these results have been obtained without any observed difference in properties between ultrasonically and conventionally fabricated parts. (Author).

As researchers seek replacements for banned, ozone-depleting foaming agents, the authors of Thermoplastic Foam Processing: Principles and Development strive to develop a better understanding of foaming processes and find solutions for day-to-day practice. This book presents the latest research in foam extrusion and physical foaming agents with a st

The objective of the ICME 2011 conference was to provide a forum where researchers, educators, engineers and government officials, involved in the general area of Mechanical Engineering, could disseminate their latest research results and exchange views on the future research directions of the field. Volume is indexed by Thomson Reuters CPCI-S (WoS). The three-volume set includes over 389 peer-reviewed papers, grouped under the chapter headings: Materials Engineering and Manufacturing Process, and Mechanical Engineering and Automotive Engineering. This timely volume will be a useful source of new ideas.
