采用半固态搅拌超声振动法制备颗粒增强镁基纳米复合材料，并对其进行挤压。结果表明，随着挤压温度从250℃升高到350℃，SiCp/AZ91纳米复合材料中的颗粒逐渐细化，纳米碳化硅颗粒条带数量减少；在相同的挤压条件下，随着搅拌时间的减少，复合材料中颗粒尺寸逐渐减小，纳米碳化硅颗粒的分布得到改善。随着挤压温度的升高，纳米复合材料的屈服强度和极限拉伸强度逐渐提高。通过减少搅拌时间，制得的纳米复合材料的拉伸强度得到了显著提高。
Particulate reinforced magnesium matrix nanocomposites fabricated by semisolid stirring assisted ultrasonic vibration were subjected to extrusion. The results showed that grains of matrix in the SiCp/AZ91 nanocomposites were gradually refined while the amount of SiC nanoparticle bands was decreased with the extrusion temperature increasing from 250 to 350°C. Under the same extrusion conditions, the grain size of the matrix was gradually decreased while the distribution of SiC nanoparticles was improved in the extruded nanocomposites fabricated by decreasing the stirring time. The yield strength and ultimate tensile strength of the nanocomposites were gradually enhanced with increasing the extrusion temperature. Significant improvement of tensile strength was obtained in the nanocomposites fabricated by decreasing the stirring time.
