Abstract A variety of metals,Fe,Ni,Mo,Zr,Nb,Cr,V,Ta,and their alloys have been tested with regard of their corrosion resistance against liquid Al-Mg alloy,which is used as a solvent for extracting fission products.Experiments were carried out at 650℃ for durations of 50-500 hours.The corrosion resis- tance was evaluated by the thickness of diffusion layer measured with metallo- graphic examination and by the weight loss measurements.This work reveals that most of the metals and alloys studied are severely attacked by liquid Al-Mg alloys.However,Nb and its alloys with small amounts of alloying elements (e.g.Nb-2Al,Nb-lCr)and Ta exhibit satisfactory corrosion resistance.
