Abstract
In recent years, there has been a lot of interest in aluminum composites because of their improved mechanical properties, higher thermal stability, and lower weight than standard aluminum alloys. The thermal behavior of aluminum composites was examined during continuous heating, and thermal diffusivity and conductivity were measured.
The experimental procedure involved the reinforcement of the aluminum matrix AN EW 6061 with ceramic particles Al2O3 to create aluminum composites. The reinforcer was used in size 80 um and three different fractions of 2 mas%, 5 mas% and 8 mas%. Stir casting was used to produce the composite. The thermal characteristics of solidified composite samples were measured using the flash method during continuous heating in a protected nitrogen environment at a heating rate of 10 °C/min.
The thermal diffusivity and thermal conductivity values were found to be slightly lower compared to the matrix alloy. In addition, as the mass fraction of reinforcement in the composite increased, the thermal diffusivity values decreased, while the thermal conductivity values first decreased and then increased.
