The erosion behavior of austempered ductile irons austenized at different temperatures was studied.The results indicate that the erosion rate well correlates with the mechanical properties.At high impact angles,increasing ductility and mechanical energy density results in decreasing erosion rate,whereas increasing hardness reduces the erosion rate at low impact angles.

The erosion behavior of austempered ductile irons austenized at different temperatures was studied. The results indicate that the erosion rate well correlates with the mechanical properties. At high impact angles, increasing ductility and mechanical energy density results in decreasing erosion rate, due to hardness reduces reduces the erosion rate at low impact angles.
