The Effect of Particle Size and Electromagnetic Stirring Parameters in Composite Material of SiC Based on Aluminum

Sic颗粒掺入金属基复合材料形成一种高性能与低成本的金属基复合材料,被认为是应用范围最广、开发和应用前景最大的一类金属基复合材料。铝基复合材料的增强颗粒尺寸和制备工艺直接影响着材料的组织及性能,因此研究增强颗粒物的尺寸和制备参数对铝基本复合材料组织的影响具有重要作用。本论文研究了SiC颗粒尺寸和电磁搅拌参数对Al基复合增强材料组织的影响。通过研究得出最适宜的SiC颗粒尺寸和电磁搅拌参数,对提高铝基复合材料的组织性能具有重要意义。

SiC particles doping in metal matrix composite materials can produce a metal matrix composite with high performance and low cost. The size of particles for enhancing and preparation process directly affect the me- chanical properties of the material of aluminum matrix composites, so it plays an important role that investigation on the effect of size of particles and synthesis parameters of preparing particles on aluminum. In the paper, the research results give the optimum particle size and mixing parameters, which will improve the microstructure and properties of aluminum matrix composites.
