| 摘 要： | 通过对Sn、Cu混合粉末的机械球磨，利用X射线衍射仪、差热热分析仪和扫描电镜对粉末进行了检测与分析，研究了不同球磨条件对Sn-0．7Cu合金形成的影响。结果表明，电压、球料比及球磨时间对Sn-0．7Cu合金的形成有很大影响。对于Sn-Cu二元系，其机械合金化反应机制是通过机械诱发原子扩散，使原子间发生置换固溶和晶界溶解，而逐渐形成Cu4Sn5等合金相的。

| Abstract: | The mixed Sn and Cu powder was milled by mechanical ball milling.The milled powders were analyzed by X-ray diffraction,differential thermal analyzer and scanning electron microscope.The effect of ball milling conditions on the formation of Sn-0.7Cu alloy was investigated.The results showed that voltage,ball-to-powder mass ratio,and milling time affect the formation of Sn-0.7Cu alloy significantly.The mechanism of mechanical alloying Sn-Cu was that the mechanically-induced atom diffusion drives substitutional solid solution and interface dissolution,as a result of which Cu_6Sn_5 was formed. |
