Abstract

The fabrication of Al-AlN composites by gas melt reactions has great potential since it involves a simple manufacturing process and has the ability to achieve a superior composite interface. This paper describes a velocity field analysis of an agitator system for the fabrication of Al-AlN composites. Based on the analysis, while sufficient particle velocities were achieved in the lower end of the stirrer when the AlN fraction of the composites was < 10%, the average velocity of AlN particles decreased rapidly with agitation time. However, the velocity field was not sufficiently developed with higher AlN fractions. Therefore, it is necessary to modify the stirring conditions for high fraction Al-AlN composite materials.


Keywords: Al-AlN composite, Velocity field, Agitator, Gas reaction control
