摘要: The present study focuses on analysing and modelling the influence fatigue behaviour of surface a hot-forged C70 connecting rod which undergoes shot-blasting treatment. heavily affects thus properties. In addition, forging process introduces large defects also have an effect strength. So as to be able determine aspects integrity are most influential in fatigue, additional states were generated by shot-peening as-forged surface. various thoroughly characterised then tested high cycle bending. studied roughness defects, residual stresses, microstructure.
