| 復(fù)合材料相組成分析表明，在復(fù)合材料制備過程中，界面發(fā)生輕微的化學(xué)反應(yīng)，生成高強(qiáng)硬質(zhì)的Mg2Si相，通過SEM分析、布氏硬度、透射分析、拉伸力學(xué)性能測(cè)試方式，探究碳化硅顆粒對(duì)復(fù)合材料的顯微組織及微觀性能的影響，結(jié)果表明，同AZ91相比，SiC顆粒增強(qiáng)AZ91復(fù)合材料硬度提升了約16.4%，SiC/AZ91D鎂合金具有較好的力學(xué)性能，材料硬度的提高，主要是由于碳化硅顆粒與基體合金AZ91進(jìn)行載荷分配，作為第二相的碳化硅顆粒促使了位錯(cuò)強(qiáng)化,使材料的硬度得到顯著提高。 |

| 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. |

The phase composition analysis of the composite demonstrates slight chemical reaction on the interface could produce the Mg2Si phase with high strength and hardness in 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 and tensile mechanical properties test are used, and the result indicates that SiC particles have enhanced the hardness of AZ91 composite 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. As the second phase, silicon carbide particles help AZ91 with dislocations strengthening, which in turn highly improves the hardness of the composite. |

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. |
