Cavitation-induced erosion of ordered and disordered Cu < inf> 3 Au
The effect of the order-disorder transformation on the resistance of Cu3Au to cavitation-induced erosion has been studied. The general weight loss rate vs. time behavior is similar for the alloy in both the initially-ordered and initially-disordered conditions; however, after the initial stage the erosion rate of the initially-ordered alloy is only about one-half that for the disordered alloy. Analysis by X-ray diffraction shows that the surface layers of the ordered alloy are disordered by mechanical deformation prior to material removal. It is suggested that the homogeneous nature of the slip process in ordered alloy causes it to erode at a lower rate than the disordered alloy which deforms by inhomogeneous slip. In both the ordered and disordered conditions the final material removal appears to involve contributions from intergranular failure. © 1976.
