| Abstract Scope |
Steel is widely recycled, accounting for 40% of global crude-Steel production. However, majority of metallic components approaching the end of their service-life have good physical dimensions but poor mechanical properties due to fatigue damage. Hence, there’s a great potential to use such components beyond their "end of service-life", and this can be successfully done if they can be rejuvenated without modifying their overall microstructures. Recently, electro-pulsing treatment (EPT) has been investigated to improve mechanical properties in several materials. This study deals with utilising EPT to reset the microstructure of the 316L Stainless Steel after fatigue deformation. Impact of several parameters of EPT were investigated to see the influence on extending the fatigue life of 316L samples. We employed 5 kJ and 8 kJ energy on different interrupted fatigue tests to get rid off fatigued microstructure, and also portrayed the increment in fatigue life post-EPT treatment. |
