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.
On the ordinary rotary bending fatigue tester, the metal material was subjected to a composite test of rotary bending and thermal fatigue. The thermal fatigue performance of the ductile iron roll material was tested, and the failure behavior and failure mechanism were analyzed.
