High entropy
High-entropy (HE) alloys are recently developed alloys defined as solid solutions (SS) containing at least five principal elements in equiatomic or near equiatomic compositions. HE alloys usually possess simple FCC and/or BCC structures instead of complex structures. Mechanical alloying (MA), a dry high-energy ball milling process, has been one of the routes to synthesized HE alloys. Having the particular characteristic of form SS from elemental powders, by this technique is possible to obtain advanced materials in nanocrystalline scale, which can exhibit excellent properties like high hardness and elevated thermal stability. Since the development of HE alloys, AlCoCrCuFeNi alloy system has been widely studied in terms of microstructure and mechanical properties. Evidence of Cu segregation in as-cast alloys was observed [1]. Also, in HE alloys produced by MA, Cu remains no incorporated into the SS formed [2]. Research is being conducted to study microstructural and mechanical features of the mention alloy system using Ti, element with HCP structure, instead of Cu.
