- Abstract
The thermal expansion behaviours of aluminium composites reinforced by ABOw with and without Bi2O3 coating are studied. The results show that the coating could influence the thermal expansion behaviour of composite. The coefficient of thermal expansion (CTE) of the composite with Bi2O3 coating is higher than that of the composite without coating. In addition, the heat treatment influences the thermal expansion behaviours of composite with Bi2O3 coating. The CTEs of the heat treatment composites are lower compared to as cast composite. At the same time, the quenching can boost the CTE of the composite compared with the annealing.
