在ZA35合金中加入纳米TiC颗粒作为增强相,采用电磁搅拌制备了纳米TiC颗粒增强锌基复合材料。通过力学性能测试确定了纳米TiC颗粒的适宜加入量,分析了TiC对颗粒增强锌基复合材料力学性能的影响。结果表明:电磁搅拌可细化合金,随着电流的增加,枝晶细小,但电流超过100A时,细化效果减弱;当纳米TiC颗粒加入量为7.5%时,锌基复合材料的抗拉强度达到410.5MPa,伸长率达到4.67%。
In the ZA35 alloy nano-TiC particles as reinforcing phase, the use of electromagnetic stirring nano-TiC particle reinforced zinc matrix composites. Through the mechanical property test, the appropriate dosage of nano-TiC particles was determined, and the effect of TiC on the mechanical properties of the particle reinforced zinc matrix composites was analyzed. The results show that the electromagnetic stirring can refine the alloy, and the dendrite is small with the increase of current. However, when the current exceeds 100A, the refining effect is weakened. When the nano-TiC particles content is 7.5%, the tensile strength Reached 410.5MPa, elongation reached 4.67%.
