Influence of Heating Temperature on Morphology of Eutectic Carbide and Impact Fatigue Property of Low Alloy Wear Resistant Cast Iron
The influence of heating temperature on morphology of eutectic carbide and impact fatigue property of low alloy wear resistant cast iron were studied by OM, SEM and impact fatigue tester. The results show that the network eutectic carbides are broken and blocks carbides are increased gradually with increasing of heating temperature, and the cast iron can obtain higher impact fatigue property when normalizing at 950 ℃ for 3 h.
