Summary

Several aluminum alloys have been reinforced successfully with ceramics particles. After mechanical alloying of a powder mixture of aluminum and reinforcement, hot extrusion give a sintered material with low porosity. Besides hardness or wear resistance, other properties can be improved with these ceramic additions.

The present work shows the result of dimensional change of 2014 aluminum alloy with different carbides additions using a differential dilatometer, under different atmospheres and heating cycles. Samples of 5 mm in diameter were obtained by cutting of hot extruded bars. These were obtained from green compacts of a mixture of powder obtained by mechanical alloying.

Also microhardness and scanning electron microscopy has been carried out before and after heating cycle.
