Optimization in Friction Stir Welding: With Emphasis on Thermo-mechanical Aspects

Posted by: | Comments (0)
Thursday, September 29th, 2011

Product Description
This book deals with the challenging multidisciplinary task of combining variant thermal and thermo-mechanical simulations for the manufacturing process of friction stir welding (FSW) with numerical optimization techniques in the search for optimal process parameters. The FSW process is characterized by multiphysics involving solid material flow, heat transfer, thermal softening, recrystallization and the formation of residual stresses. Initially, the thermal models… More >>

FRICTION STIR WELDING OF ALUMINIUM ALLOYS: Microstructure-Property Development

Posted by: | Comments (0)
Sunday, September 18th, 2011

Product Description
Friction Stir Welding (FSW) is known to result in a complex microstructural development, with features that remain unexplained, such as: the formation of the onion rings structure. Moreover, various microstructural factors have been suggested to control the strength in Al-Mg AA5xxx welds, without identifying their relative contribution. Furthermore, the influence of the basemetal microstructural parameters (e.g. grains, intermetallic particles, stored energy)… More >>

Wednesday, December 15th, 2010

Product Description
Webster’s bibliographic and event-based timelines are comprehensive in scope, covering virtually all topics, geographic locations and people. They do so from a linguistic point of view, and in the case of this book, the focus is on “Friction Welding,” including when used in literature (e.g. all authors that might have Friction Welding in their name). As such, this book represents the largest compilation of timeline events associated with Friction Welding when it is … More >>

Real-Time Quality Monitoring in Friction Stir Welding: The Use of Feedback Forces for Nondestructive Evaluation of Friction Stir Welding

Posted by: | Comments (0)
Friday, May 14th, 2010

Product Description
The focus of the book is to demonstrate a feasibility study for detecting wormhole defects using the frequency spectrum, phase space, and time spectrum of feedback forces in real-time. It is asserted here that the oscillations of the feedback forces are related to the dynamics of the plasticized material flow and that the feedback forces can provide useful information for detecting wormhole defects. Two real-time feedback-force evaluation algorithms are developed fo… More >>

Friction Stir Welding of Metal Matrix Composites: The Joining of Al 6061/SiC/17.5p Using Diamond Coated Tools

Posted by: | Comments (0)
Saturday, April 10th, 2010

Product Description
Friction Stir Welding (FSW) is a solid-state joining process developed by TWI. The large axial forces associated with this process are typically cited as one of the major obstacles to its widespread application. The primary objective of this research is to quantify the reduction of axial force through use of diamond coatings of FSW tools. Results of welds for coated and uncoated tools on Al 6061 are compared. The goal is to produce friction stir weld… More >>
