In-situ processing of Al alloy composites

In-situ processing of discontinuously reinforced Al alloy composites (DRACs) by gas-bubbling method was investigated in this paper. Fine SiC and AlN particles were synthesized by bubbling C-bearing and N-bearing gases respectively. These results show that processing of DRACs through in-situ gas-bubbling route is technically feasible. Compared with conventional processing techniques, this method has the potential to produce DRACs with better microstructure and properties while with lower cost.
