The effect of normalizing on microstructure, strength, impact toughness and ductile-brittletransitiontemperature of FAS390Q axle housing steel was studied.
研究了正火处理对FAS390Q桥壳钢显微组织、强度、冲击韧性和韧脆转变温度的影响。

The specimens with Widmanstatten structure have higher impact strength and lower ductile-brittletransitiontemperature than those with equiaxial granular ferrite structure.
有魏氏组织的试样较呈等轴铁素体的试样有更高的冲击韧性和更低的韧脆转变温度。

High manganese steels undergo a ductile to brittletransition at low temperature, which is accompanied by a change in the fracture mechanism from dimple fracture to intergranular fracture.
