| 英文摘要 | The sub-micrometric Sic particulates reinforced pure aluminum metal matrix composite (Al MMC) was fabricated by a powder metallurgy technique. The microstructure of the Al MMC was observed, and the tensile properties were measured. The results show that the 15% SiCp (150 nm)/Al MMC exhibits an ultimate tensile strength of 342.3 MPa and a yield strength of 272.4 MPa, these values are 89.0% and 117.9% higher than those of the corresponding matrix respectively, and the elongation of the Al MMC is 6.3%. The tensile fracture surface shows that the damage mechanisms of the Al MMC involve interfacial failure and brittle damage of SiC agglomeration. The reason that the Al MMC has much higher yield strength is the change of matrix microstructure. Dislocation density and Orowan strengthening mechanisms are used to evaluate their effects on the matrix yield strength, and the predicted result is consistent with experimental result. |
