Abstract

The objective of this article is to provide a review of friction stir processing (FSP) technology and its application for microstructure modification of particle reinforced composite materials. The main focus of FSP was on aluminum based alloys and composites. Recently, many researchers have investigated this technology for treating other alloys and materials including stainless steels, magnesium, titanium, and copper. It is shown that FSP technology is very effective in microstructure modification of reinforced metal matrix composite materials. FSP has also been used in the processing and structure modification of polymeric composite materials. Compared with other manufacturing processes, friction stir processing has the advantage of reducing distortion and defects in materials. The layout of this paper is as follows. The friction stir processing technology will be presented first. Then, the application of this technology in manufacturing and structure modification of particle reinforced composite materials will be introduced. Future application of friction stir processing in energy field, for example, for vanadium alloy and composites will be discussed. Finally, the challenges for improving friction stir processing technology will be mentioned.

Highlights

Friction stir processing (FSP) is a solid state process known for its ability to modify microstructures and provide improved properties over conventional processing technologies [1,2,3,4,5,6,7,8,9,10,11,12]
The results show that the increasing in number of friction stir processing (FSP) passes causes more uniform distribution of nano-sized alumina particles
Some of the properties, for example, hardness is high for FSP materials

Summary

Introduction

Friction stir processing (FSP) is a solid state process known for its ability to modify microstructures and provide improved properties over conventional processing technologies [1,2,3,4,5,6,7,8,9,10,11,12]. The development of friction stir processing (FSP) is based on the friction stir welding (FSW) technology. The friction caused by the tool heats up the materials around the pin to a temperature below the melting point. In FSP, a specially designed rotating pin, as shown, is first inserted into the material to be processed with a proper tool tilt angle and move along the designed paths. That is why in some literatures, the uses of the two terms are interchangeable. They do have different purposes in practical applications. The goal of FSW is to join two plates together, whereas FSP aims at modifying the microstructure of a single workpiece or multiple workpieces
