Influences of solution treatment, deformation strain, and nanometric Al2O3 particulate on hardness for nanometric Al2O3 particulate reinforced Al alloy matrix Composites manufactured by casting

摘要：

　　The influences of solution treatment,deformation strain,and nanometric Al2O3 particulate on hardness for nanometric Al2O3 particulate reinforced Al alloy matrix Composites manufactured by casting were investigated.The result showed that both the hardness of AL matrix and the hardness of the composites increased dramatically with increasing solution temperatures.The hardness increased slightly with increasing deformation strain for the composites.The hardness of the composites is higher than the AL matrix after the same deformation and heat treatment.Microstructure observation revealed that the grain sizes of the composites increased with increasing solution temperature and decreased with more severe deformation.
