【摘要】 探讨了微量的稀土元素Er和过渡族元素Mn对Al-Mg合金铸态、均匀化态、热轧及冷轧态组织和常温力学性能的影响,分析了它们在合金中的存在形式以及相互之间的作用。结果表明,稀土元素Er和过渡族元素Mn对改善合金力学性能是有益的,但是当它们共同加入时,强化效果会削弱,影响单一元素各自单独发挥作用。更多还原

【Abstract】 Effects of trace Er and Mn on the microstructures and mechanical properties of as-cast,homogenized,hot-rolled and cold-rolled alloys were investigated.Their existing forms and interactions with each other were studied.The results showed that the element erbium and manganese had good effect on improving the Al-Mg alloy mechanical properties,but the strengthening effect would be weakened when they were added together,and influenced the function of individual element.更多还原
