Development and characterization of A359/AlN composites for automotive applications
چکیده انگلیسی
A359/AlN composites were successfully manufactured using stir and squeeze techniques. Microstructure, aging behavior, hardness, thermal and mechanical properties were inspected. Microstructural investigation showed a uniform distribution of AlN particles in A359 matrix and a significant reduction in porosity. Interfacial analysis indicated considerable bonding between A359 matrix and AlN particles. Hardness, ultimate compressive and yield strength increased as AlN content increased from 5 to 15 wt%. Furthermore, aging process of A359/AlN composites was accelerated by increasing AlN content. Differential thermal analysis (DTA) revealed that A359/AlN composite had lower eutectic temperature than that of A359 alloy. Finite element modeling showed the dependence of the stress induced in A359/AlN composite on the distribution of AlN particles.
