Erosion of solid-solution-strengthened alloys

In order to determine the effect of solid solution strengthening of ductile metal alloys on their erosion resistance, both iron and copper base alloys were melted and room temperature erosion tested in the as-cast and rolled forms. It was determined that solid solution strengthening of eight different alloys did not improve their erosion resistance and, to some degree, had a small negative effect on their performance. There was relatively little difference in their erosion rates over a wide range of hardness. There was also essentially no difference in the erosion rates of as-cast and rolled versions of the same alloys.
