Abstract Scope |
The search for a high entropy alloy that would withstand the conditions in an aeroplane turbine lead to the Al10Co25Cr8Fe15Ni33Ti6 compositionally complex alloy which combines good strength and ductility. Inspired from superalloy design the authors started to search for trace elements that would further improve the mechanical properties of the alloys. It turned out that the addition of two elements, i.e. Hf and W, would lead to a well-tunable microstructure in terms of precipitate shape and lattice misfit, as was determined via scanning and transmission electron microscopy and synchrotron x-ray diffraction. The direct link of these characteristics to the mechanical properties could be verified via creep experiments. |
