چکیده
|
Widely investigated alcocrcufeni high entropy alloy has been chosen for optimization of the microstructural and mechanical properties. different paths have been chosen for optimization; namely the decrease of segregating element cu, the increase of oxidation protective elements al and cr and the approach towards a γ-γ' microstructure as in ni-based superalloys. microscopical observation has been made for each optimization step and compared with results obtained by vickers microhardness measurements. out of five derivate alloys: alcocrfeni, al23co15cr23cu8fe15ni16, al8co17cr17cu8fe17ni33, al8co17cr14cu8fe17ni33mo1ti1w1 and al10co25cr8fe15ni36ti6, the most promising one has been chosen for further investigation.
