| Abstract Scope |
High-level plastic deformation can lead to the decomposition of cementite lamellae within pearlitic steels, where dislocations shear the carbides and push carbon into the ferrite matrix. This process results in one of the strongest steels known to date. The elevated hardness levels observed in such steels suggest exceptional wear resistance, possibly expanding their potential applications. Ultimately, in this study, we focus on experimentally assessing the wear behavior of severely cold rolled pearlitic microstructures. To investigate the impact of carbide decomposition on wear rates and friction coefficients, we employed in-situ scanning electron microscope microscopic scratch tests using a pico-indenter. Our findings reveal promising correlations between the microstructural evolution and the wear resistance of decomposed carbides. These insights provide valuable guidance for future design approaches aimed at enhancing the performance in wear-prone applications. |
