摘　　要：以无线自组网结构用ZL101铝合金为研究对象,分析了无振动、垂直振动、水平振动和复合振动方式下合金消失模铸件的凝固组织和力学性能的变化规律。结果表明,机械振动后合金的组织得到明显细化,尤其是在垂直振动方式下合金的晶粒尺寸最小,针孔率最低,合金的抗拉强度最大,是较为适宜的振动方式;在不同厚度的铸件振动过程中,铸件厚度越大则振动细化效果越显著。Taking ZL101 aluminum alloy as research object, the microstructure and mechanical properties of die casting alloy was analyzed under the condition of without vibration, vertical vibration, horizontal vibration and composite variation modes . The results show that, the mechanical vibration can refine the microstructure obviously, especially in the vertical vibration mode. The alloy can get the minimum grain size, lowest pinhole rate and highest tensile strength, which is the optimized vibration mode. During the vibration process of the casting with different thickness, the thicker of the casting, the more obvious of vibration refinement effect.
