Influence of solution treatment and cool rolling deformation on the microstructure and electrochemical performance of the Al-Ga-Mg-Mn-Bi anode alloy was investigated by measuring the impedance spectroscopy, polarization curve, free-corrosion rate, etc. The results show that: in comparison with the cast alloy, the quantity of the second phase, the free-corrosion rate and the hydrogen evolution rate of the solution-treated alloy were greatly reduced, while the amount and size of corrosion pits were also reduced with a negative shift of its potential of constant- current discharge; after cool rolling deformation the alloy exhibits a rather uniform corrosion morphology with small pits and also a negative shift of its potential of constant-current discharge.
