Aluminum alloy 6061 and 20TiC/6061 aluminum matrix composites were prepared by the microwave sintering

and microstructures and properties of the two materials prepared were investigated at different sintering temperatures.The results show that with the increase of sintering temperature

metallurgical bonding ability of aluminum alloy 6061 prepared by microwave sintering is improved

and microstructure and properties of the materials are also improved at the sintering temperature range

meanwhile

the final relative density reaches approximately 96%.With sintering at 560 ℃

fine reinforcement particles with sound bonding with matrix are uniformly distributed in the 20TiC/6061 composites.XRD analysis shows that only single Al phase exists in 6061 alloy

and matrix phase Al and reinforcement TiC exist in the composites with absence of other phases.
