APPLICATION OF POTENTIOSTATIC AND GALVANOSTATIC TECHNIQUES TO THE STUDY OF INTERGRANULAR CORROSION IN HIGH STRENGTH ALUMINUM ALLOYS

摘要

The effect of slow quenching following solution heat treatment on naturally aged Al-Cu-Mg alloy can be detected by corrosion potentials and accelerated corrosion tests for intergranular corrosion and stress corrosion susceptibility. Faster quenching rates give on indication of the existence of any continuous anodic paths until a stress is applied.
