| Abstract Scope |
In this work the susceptibility to intergranular corrosion of (i) different wrought aluminium alloys and (ii) various compositions of the same standard alloy was investigated with electrochemical and metallographic methods. The main difficulty in predicting the intergranular corrosion behaviour based on the results of the electrochemical corrosion test is in the fact that, even when performed with the same chloride medium and under the same or similar experimental conditions, electrochemical fatigue results in a different corrosion attack on the surface of aluminium-based products. On the other hand, the measure of the intergranular corrosion is often under the operator’s influence, which is not the case in electrochemical corrosion testing. Therefore, the purpose of this study was to correlate the results of these two methods, enabling the accumulation of the appropriate filtered and structured data for high-quality data-driven predictions of the most stress-corrosion-resistant compositions of wrought aluminium alloys. |
