Attempts have been made to clarify the cause of blowouts of score on aluminum alloy 5182 EOE in a carbonated soft-drink solution at 38±2°C. Polarization measurements and metallurgical observation indicated that the blowouts is caused by pitting of groove of the score. It is pointed out that the exposure of intermetallic compounds containing copper is detrimental to the pitting of 5182 in a carbonated soft-drink solution concentrated by vaporizing.
