摘要: 使用高压反应釜对Al-Mg-Li-Zr合金粉末的水反应性能进行了研究，通过对反应体系的温度–时间(T-t)曲线进行分析，提取出了反应启动温度、反应时间、放热温升与平均升温速率四个特征参数，重点研究了不同种类离子对Al-Mg-Li-Zr合金粉末水反应性能的影响。结果表明，相较于蒸馏水，大部分盐溶液均使得Al-Mg-Li-Zr合金粉末的水反应启动温度降低。硝酸根、硫酸根、氯离子、钾离子与钠离子均对Al-Mg-Li-Zr合金粉末的水反应起到促进作用，其中，KNO3的促进效果最好，而氟化盐则明显抑制了Al-Mg-Li-Zr合金粉末的水反应。
Abstract: The water reaction performance of Al-Mg-Li-Zr alloy powder was studied in a high-pressure reactor. Through the analysis of the temperature-time (T-t) curve of the reaction system, four characteristic parameters, namely, reaction starting temperature, reaction time, exothermic temperature rise and average temperature rise rate, were extracted. The effects of different kinds of ions on the water reaction performance of Al-Mg-Li-Zr alloy powder were emphatically studied. The results showed that compared with distilled water, the starting temper-ature of the water reaction of Al-Mg-Li-Zr alloy powder was reduced by most salt solutions. Nitrate, sulfate, chloride, potassium and sodium ions all promoted the water reaction of Al-Mg-Li-Zr alloy powder, among which KNO3 was the best, while fluoride obviously inhibited the water reaction of Al-Mg-Li-Zr alloy powder.
