Electrochemical measurements and metallurgical observations have been made to clarify the relationship between NaOH solution temperature and the dissolution behavior of Al-Fe alloy. Etching weight loss was measured for Al-Fe alloy specimens dipped into 3%NaOH+1%NaAlO2 solutions at four temperatures (298, 313, 333 and 353K). As solution temperature rose, etching weight loss increased exponentially. It was found that etching weight loss was more strongly affected by solution temperature than by NaOH concentration.
