Abstract of the dataset | The influence of work hardening on the fatigue behaviour of high-purity copper was investigated using commercially available sheet material (3 mm thickness, as-delivered, no additional rolling or heat treatment) in three strength classes (indicated by their R-number, a measure of minimum tensile strength): R240 (two independently supplied batches, R240-1 and R240-2), R290, and R360. These material states are representative of copper conductors used in electrical applications such as traction motors, generators, and battery systems. For each material state, the dataset comprises: 1. Microstructural characterization by electron backscatter diffraction (EBSD). 2. Quasi-static (monotonic) tensile tests in strain control, using the same specimen geometry as the fatigue specimens (10 mm gauge length; not a standard tensile geometry, so results beyond necking are not comparable to standardized tensile tests). 3. Load-controlled fatigue (Wöhler/S-N) tests on smooth, unnotched specimens at several load ratios, used to quantify the combined effect of mean stress and work-hardening state on fatigue strength. Run-out was defined at 5 10^7 load cycles. | |
