Abstract Scope |
HEA thin films could be processed using a multiple beam sputtering system in PVD, which does not require preliminary manufacturing of HEA targets. Instead, it uses commercially pure metal targets. This method also demonstrates the capability of multiple beam sputtering techniques to produce compositional gradient samples with a wide range of elemental concentrations, enabling combinatorial analysis of multiple elements high-entropy alloy. The microstructure and the mechanical properties of the gradient sample were studied in detail. Synchrotron X-ray diffraction was used to create a diffraction map for the gradient sample. Therefore, we can examine the changes of the microstructure as a function of the chemical composition. The microstructure at the points of interest was further investigated by TEM. The chemical composition of the sample was mapped by XRF and EDS. The mechanical properties were characterized by nanoindentation. |
