金属材料旋弯—热疲劳的试验研究

Experiment research on rotational bending together with thermal fatigue for metal

在普通旋弯疲劳试验机上,对金属材料进行了旋弯—热疲劳的复合试验,测试了球铁轧辊材料的热疲劳性能,分析了其失效行为和破坏机理.

This paper introduces a testing method of rotational bending together with thermal fatigue for metal material.The author measures thermal fatigue properties of nodular iron roller,and analyzes its deactivating behavior and fracture mechanism.
