Single-crystal Ni-base superalloys are multi-element (> ~ 10 elements) alloys that are critical for the parts of high-temperature turbine engines. Over the years, multiple generations of superalloys were developed, where the latest compositions involve dense and Rare-Earth elements such as Re and Ru (up to 6 wt.%), making them heavier and costlier. Hence, it has a direct negative impact on engine efficiency and higher CO2 emissions.  

During an earthquake, transient friction-generated heat can affect how minerals deform and thus affect the strength of the fault. Thin (0.1–1 mm-thick) mirror-like slip surfaces (fault mirrors) that form during earthquake processes and record evidence of coseismic temperature rise are thus ideal materials to investigate how the deforming volume of rock evolves over individual or multiple earthquake cycles. Here we present atom probe tomography (APT) data from two hematite fault mirrors that were collected from the footwall damage zone of the Wasatch fault zone (Utah, USA). These samples provide evidence of the nanoscale response of minerals respond to earthquake rupture and yield new insights about the dynamic evolution of fault strength throughout the earthquake cycle.
