| 摘 要： | 应用高能球磨机械合金化方法制备纳米Zn及Zn—Al合金体材料，采用拉伸实验和MDBT实验对这些材料的样品的机械性能进行测量分析．结果表明：球磨3～5h获得的Zn-0．6％Al含金具有很好的塑性．室温下球磨3h所得的纯Zn比液氮温度下球磨3h加室温球磨6h所得的纯Zn具有更好的塑性．

| Abstract: | Bulk nanocrystalline pure Zn and Zn-Al alloy can be produced by ball milling.The mechanical properties of those materials are analyzed by tensile test and miniaturized disk bent test(MDBT).The results show that Zn-0.6%(wt) Al ball milled for 3~5 hours has very good ductility.The pure Zn ball milled for 3 hours at room temperature has better ductility than pure Zn cryomilling(CM) ball milled for 3 hours at liquid nitrogen and then at room temperature(BM) for 6 hours. |
