Abstract Scope |
Surface degradation through wear is a significant cause of early failure for bearings in aerospace and industrial applications. However, wear at sliding contacts involves highly localised and fluctuating stresses, generating complex micromechanical conditions. Microstructural complexity further complicates the understanding of these processes. For example, spinodally hardened bronzes have a hierarchical microstructure including nanoscale spinodal domains and ordered precipitate phases, which contribute significantly to its wear resistance. Here, we report in situ scanning electron microscopy scratch tests and tension tests, carried out to probe the micromechanical strain localisation and damage of a spinodal bronze, and to systematically evaluate the role of microstructural constituents. |
