Abstract Scope |
The microstructure, mechanical properties and fatigue properties of Q550D with the same composition and different delivery conditions were tested and compared. The effects of different delivery conditions on the microstructure and mechanical properties were studied. The fatigue properties of two kinds of experimental steels were studied by group method and lifting method. The S-N curve was drawn. The fatigue fracture morphology and metallographic structure were detected and analyzed and the conditional fatigue limit is obtained by statistical analysis. |
