Abstract The effect of heat treatment on the anodic behaviour of the Cu-Be-Ni-Zr alloy in 65% phosphoric acid has been investigated by the potentiostatic method. Different anode states obtained by quenching from temperatures of 900,950 and 1000°C were examined under the microscope. It was found that the position and shape of the polarization curves, especially in the active and passive parts, are dependent upon the quenching temperature and colling rate. For pre-quenching temperatures up to 950°C, at which there are no appreciable changes in microstructure, the polarization curves are similar. For higher pre-quenching temperatures up to 1000°C where substantial microstructural changes occur, the active part of the polarization curves becomes more negative, by almost 100 mV, while the passivation decreases.
