Corrosion behaviour of aluminium-magnesium alloys in molten sodium

摘要

The corrosion behaviour of the Al-1/100 Mg, Al-3/100 Mg, AL-5/100 Mg and AL-3/100 Mg-0.15/100Zr alloys in molten sodium was investigated. The morphology of the corrosion products and the alloying element distribution of the specimens were analyzed by using OM, SEM and EDS. The results showed that the effects of the magnesium content and the im- mersion temperature on the corrosion of the specimens are related to β phase (Mg_5Al_8).
