The phase composition analysis of the composite demonstrates slight chemical reaction on the interface and could produce the Mg2Si phase with high strength and hardness during the process of producing composite. To explore the effect of silicon carbide particles on the composite¡¯s microstructure and its microstructural properties, ways of SEM analysis, Brinell Hardness and transmission analysis as well as tensile mechanical properties test have been adopted.The result indicates that SiC particles have enhanced the hardness of AZ91 composite by nearly 16.4% and the SiC/AZ91D magnesium alloy acquires better mechanical properties. The improvement of the hardness is mainly due to the load distribution of AZ91 base matrix with the help of silicon carbide particles. The silicon carbide particles,as the second phase,help AZ91 with dislocations strengthening, which has in turn highly improved the hardness of the composite. |

| Composite phase composition analysis shows that in the process of preparing composite materials, interface in slight chemical reaction, generate high toughness Mg2Si phase, by SEM analysis, brinell hardness, tem analysis, tensile mechanical properties test, silicon carbide particles on the microstructure of the composite and the influence of microcosmic performance, the results show that compared with AZ91, SiC particle reinforced AZ91 composite hardness increased by about 16.4%, SiC/AZ91D magnesium alloys have good mechanical properties, material hardness increases, the AZ91 alloy is mainly due to the silicon carbide particles and matrix to carry on the load distribution, as the second phase of silicon carbide particles prompted the dislocation strengthening, the hardness of materials are improved significantly. |
