Özet

SiC particulate reinforced aluminium matrix composites are attractive materials for automotive and aerospace applications because of their outstanding stiffness and strength as compared to the aluminium alloys, in addition to the low cost of particulate reinforcement. The aim of this study is to establish correlations between ultrasonic wave velocities and SiC content, microstructure and mechanical properties of SiC reinforced Al composites, Specimens were fabricated for various volume fraction and size combinations of Al and SiC particulate by hot pressing. Heat treatment and secondary deformation process were not applied. The results of ultrasonic velocity, measurements were correlated to the metallographical examinations and hardness tests.
