研究了正火温度和回火温度对ZG310 - 570铸钢组织和力学性能的影响。
Influences of normalizing temperature and tempering temperature on mechanical properties and microstructure of ZG310-570 cast steel were investigated.
结果表明，随正火温度的提高，铁素体数量减少，硬度与强度提高，塑性与韧性降低。
The results show that as the normalized temperature is increased, the volume fraction of ferrite decreases, hardness and strength increases, plasticity and ductility decreases.
扫描电镜分析表明：在相同的保温时间内，随正火温度的升高， 片层状珠光体越来越密集。
The result of SEM analysis shows that, within the same holding time, with normalizing temperature increasing, the layer-mesostructure is denser and denser.
