Effect of Austempering Heat Treatment on Erosive Wear of Austenite Ductile Iron
The austempering heat treatment,erosive wear test and mechanical properties test of ductile iron were carried out.The influences of austempering heat treatment on erosive wear properties of ductile iron were studied.The results show that the hardness increases substantially after austempering heat treatment.The impact toughness of ductile iron increases after erosive wearing.The improving of the matrix hardness contributes to reduce the drop of graphite structure.
