Research status of preparation techniques of nano - reinforced aluminum matrix composites

Nano - reinforced aluminum matrix composites are the advanced, promising and high - technology composites. The preparation techniques of the composites can be divided into six kinds, such as in - situ reaction, rapid solidification, severe plastic deformation, high energy ball milling, sputtering and sol - gel. This paper reviews the investigation status of its preparation techniques and the recent research achievements. The mechanisms, characteristics, application ranges and levels of the development about these preparation techniques are generally analyzed. Many novel materials have been synthesized by these techniques. These materials possess excellent properties in mechanics, physics and chemistry. The advantages and disadvantages of these techniques are synthetically evaluated. The application status and the future development tendency of the preparation techniques are discussed.
