Synthesis and Characterization of In Situ AlN Reinforced Magnesium Matrix Composites

Abstract:

In situ Mg-AlN composite has been synthesized by nitrogen gas bubbling method. The morphology of the particles is found to be hexagonal by SEM. The size of the AlN particles is found to be in the range from nano, submicron to a few microns. XRD analysis of the samples confirms the formation of AlN in the melt. Further, the grain size of the magnesium matrix has been reduced by the presence of AlN particles. Hardness of the composite is significantly increased in the particle rich area due to the presence of hard AlN particles.
