摘　　要：以自制的高硅含量过共晶Al-30Si为研究材料,采用低过热度浇注弱电磁搅拌这种新型半固态浆料制备技术制得了相应的半固态试样。重点研究了各制备参数对试样硬度、磨损性能和热稳定性能的影响,以期为该新型半固态制备技术的应用和Al-30Si材料的深度开发提供指导。The self-made hypereutectic Al-30Si alloy is studied in this paper. By means of low superheat pouring low intensity electromagnetism stirring which is a new type of semi-solid slurry preparation, the semi-solid Al-30Si alloy slurry is prepared and the effect of treating parameters on the hardness, wearing performance and thermal stability of samples is studied. The research process is important for this new semi-solid technology to widen the application field and the results can be provided for the deep development of Al-30Si materials.
