Abstract

The Effects of austempering duration and silicon content on the particle erosion wear resistance of high strength upper bainitic ADI were characterized. The results showed that the amount of retained austenite dominantly affects tensile strength and variation of wear resistance. For a sample with higher silicon content, the austempering duration should be prolonged to ensure complete bainitic transformation. In addition, a tiny increase in carbide formation can certainly play an important role in debasing tensile strength and erosion wear resistance. This results in an alternation in erosion behavior. However, hardness cannot be correlated to wear resistance. Erosion-induced phase transformation of retained austenite phase will eventually produce e-carbide, which thus promotes the erosion wear rate.
