| 摘 要： | 研究了稀土Nd对AM60镁合金组织的影响,并分析析出相及其对合金力学性能的影响.结果表明,在AM60合金中加入稀土Nd元素能有效地细化合金组织,使Mg17A112相分离变细;Nd元素优先与合金中的A1元素反应生成二元高熔点A111Nd3相:适量的稀土Nd能有效提高合金的抗拉强度、屈服强度和延伸率;过量的稀土Nd则会消耗合金中更多的A1元素和导致A111Nd3相粗化,使合金的力学性能下降;力学性能测试结果表明,AM60-0.9Nd具有最高的抗拉强度(230 MPa)、最高的屈服强度(127 MPa)和最高延伸率(14%),分别比基体合金提高28%、48%和250%.

| Abstract: | The microstructure changes brought by the addition of Nd element to AM60 magnesium alloy were studied,the precipi-tating phases were identified and their influences on the mechanical properties of alloys were investigated. Results show that Nd addition makes the refinement of microstructure of the AM60 alloy,and decreases the size of Mg17Al12 phase. Nd element takes a priority to react with Al element over Mg,Mn and Zn forming binary phase Al11Nd3 with high melting point. Certain content of Nd can increase ... |
