| 摘 要： | 研究了球墨铸铁材料(EN-GJS500-7)热等静压处理前后疲劳性能的变化,并分析了珠光体、石墨、铁素体含量随热等静压工艺的变化及其对球墨铸铁疲劳性能的影响。结果表明,热等静压处理后如果珠光体含量增加而铁素体含量减少,则材料抗疲劳性能增强;反之,材料疲劳性能降低。

| Abstract: | The fatigue property of ductile iron(EN-GJS500-7) prepared by hot isostatic pressing(HIP) was compared with that before heat treatment.The contents of pearlite,graphite and ferrite were changed with different HIP process.The influence on the fatigue properties of ductile iron with HIP process was discussed with the changes of their microstructures.The results show that if the content of pearlite increases and the content of ferrite decreases after this process,the fatigue resistance property improves,and vi... |
