Fracture initiation in FCC and BCC metals during tribology
Our aim is to better understand the crack initiation mechanism during single stroke experiments and the effect of grain orientation on crack formation in FCC and BCC metals. The microscale experiments are carried out with a tribolmeter and the crack formation is studied using scanning electron microscopy (SEM) with Electron Backscatter Diffraction (EBSD) analysis, focused-ion beam (FIB) cross-sectioning and transmission electron microscopy (TEM).
The fundamental understanding of crack initiation in microscale will improve the macroscale understanding of wear and friction in engineering metals. With that knowledge we can reduce more effectively wear and friction and further the reduction of replacement costs, noise and energy consumption.
