摘要
研究了合金元素镁、硅、锆对铝在350～450℃与熔融钠反应的影.采用光镜和X射线衍射仗来观察和分析腐蚀产物的组织形貌和分布.实验结果表明,试样受熔融钠腐蚀的程度与铝中硅和镁的含量有关,在Al-3ω%Mg中加入少量晶粒细化剂锆能大大减轻其腐蚀程度.
In this research, the effects of alloying elements on the reaction between aluminium and molten sodium have been investigated. Optical microscopy and X-ray diffraction analysis were used to observe and analyze the morphology and distribution of the corrosion products. The results showed that the corrosion of the specimens by molten sodium depend on the silicon and magnesium content in aluminium, and was greatly inhibited with the addition of a small amount of the grain refiner zirconium.
