Critical Assessment 25: Friction stir processing, potential and problems

Friction stir welding and processing

Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a de...

Use of Friction Stir Processing and Friction Stir Welding for Nitinol Medical Devices Cross Reference to Related Application

(57) ABSTRACT Metallic materials may be joined utilizing a friction stir processing teclmique. The friction stir processing technique utilizes a shaped, rotating tool to move material from one side of the joint to be welded to the other without liquefying the base material.

Linear Friction Based Processing Technologies for Aluminum Alloys: Surfacing, Stir Welding and Stir Channeling

Friction Stir Processing of Aluminum Alloys: A Literature Survey

Many aluminum alloys with specific properties, like high strength, suffers from certain limitations in terms of cost and time of production, apart from the reduction in ductility. High strength accompanied by high ductility is possible with materials having fine and homogenous grain structures. Hence there arises a necessity to develop a processing technique that would produce a material with s...
