Fatigue cracking was investigated by measuring the crack closure of unaged and peak-aged Cu-2wt %Be alloy specimens in 0.05 M Cu 2+-containing 1 M ammoniacal solution using an unloading elastic compliance technique and by comparing the results with those obtained in dry air. The anodic behaviour of...
