摘要：
The effect of different contents of Son fracture toughness of railway wheel steels for high speed train has been researched. The results show that there are kinds of non-metallic inclusion when O content retaining at about 10x10(-6), such as Al2O3 inclusions and Al2O3+MnS complex inclusions and single MnS inclusions. This is connected with S content level in steel. Fracture toughness of railway steel increase obviously because of Al2O3 covered by MnS around when S content is increase to about 70x10(-6). It shows that, after Al2O3 covering by MnS around, stresses around complex inclusion decrease rapidly till disappear when analyzed by tessellated stresses theory. That is the reason of fracture toughness rise.
