Biyomedikal uygulamalar için özgün yüksek entropi alaşımlarının geliştirilmesi

High entropy alloys are solid solution alloys that contain multi-principal elements in nearly equiatomic percent. This unique concept introduces a superior combination of enhanced mechanical properties that cannot be exhibited by conventional alloys consisting of one or two principal elements. The superior properties such as high strength, high fracture toughness, excellent wear, and corrosion resistance have led to the investigation of whether the novel materials could be included in the field of medicine as biomaterials. Microstructural properties, mechanical properties and bioactivities of the high entropy alloys Ti25Ta25Hf25Nb25, Ti20Ta20Hf20Nb20Zr20, Ti20Ta20Hf20Mo20Zr20, and the medium entropy alloy CoCrMo have been evaluated to observe the potential for the fruitful use of these materials in the biomedical field.
