| Abstract: | A novel technique in which 3vol%TiB 2 and 3vol%TiC particulate-reinforced aluminum matrix composites prepared by melt in-situ reaction was introduced. The influence of a mechanical stirring technique on the microstructure of the composites was studied. It was found that a mechanical stirring is necessary for fabricating TiB 2/Al and TiC/Al composites fabricated by this technique. By taking advantage of a novel disc vane stirrer, the 3vol%TiB 2/Al and 3vol%TiC/Al composites with homogeneous particulate distribution and with sound structure have been produced. |
