Abstract
A close study of the behaviour of precipitated magnesium aluminium alloys in a corroding solution of NaCl—K2CrO4 has been carried out using potentiostatic techniques and thin film electron microscopy. The fracture surfaces of the alloys have also been studied. The experimental findings are correlated with extension measurements and a crack model is proposed to explain the failure of these alloys.
