Influence of Inclusion on Fatigue Performance Evaluation of High Strength Transmission Shaft Steel

Abstract:

Along with the improvement of surface defect and decarburizing problem, the non-metallic inclusion becomes one of the most important factors which influence the fatigue performance evaluation of metallic material. To quantitatively study this problem, two group of high strength transmission shaft steel with different inclusion level are selected to do the comparison fatigue test using stair case method. Experimental data shows that the inclusion of the metallic material will observably affect its fatigue performance. The comparative large size of Al₂O₃ inclusions with tip edge angle was found by stereo-scan and energy spectrum analysis, which were the sources of micro crack and lead the final fracture.
