The Study of Electromagnetic Steel Sheet High Cycle Fatigue Properties

Abstract:

In this study, the brand name 35CS300 and 50CS400 electromagnetic steel with tensile and high cycle fatigue properties were investigated. The specimens were prepared in rolling and transverse directions. In the first, the material basic properties were built from tensile test. The high cycle fatigue was performed under stress ratio 0.1 and two sampling direction. The tensile result showed that the specimens in rolling direction (L) are slight greater than in transverse direction (T). About the fatigue test results, the 35CS300 and 50CS400 sampling direction had less effect in fatigue limit. The fracture mechanism was showed that 35CS300 has void and brush like pull out under ductile failure. But the results showed in the 50CS400 specimens had splitting fracture surface with brittle fractograph. The electromagnetic steel surface of the insulating layer under dynamic fatigue loading would cause fragmentation; if the electromagnetic steel for long-term use will reduce the efficiency.
