Özet
High entropy alloys are promising engineering materials due to their superior properties. The most striking properties of high entropy alloys are that they can have high corrosion resistance and high hardness properties simultaneously. However, most of the traditional high entropy alloys have very high density, which may disable their widespread use. In this study, it was aimed to obtain low density medium and high entropy alloys by using metals with low densities as the major alloying elements. The densities of the produced alloys varied between 3.2 and 3.9 g/cm(3). During the casting procedure, Al, Mg, Si, Mn, Cu, Sn, Zn elements were used. In this study, medium and high entropy states of systems containing five and six elements were investigated. The designed and produced alloys were designated as Al45Cu15Mn7Mg10Si13Zn10, Al-75(MgCuMnSiZn)(5), Al50Cu10Sn5Mg20Zn15 and Al-80(MgCuSnZn)(5). The alloys were produced by conventional casting method in an induction furnace under protective gas atmosphere. Microhardness, microstructure analyses, compression and wear tests were performed. Higher hardness and wear resistance were achieved compared to conventional alloys. The hardness of the alloys varies between 243 and 348 HV. Thanks to its relatively low density, high strength and wear resistance, the produced alloys can be regarded as promising engineering materials for the use in future applications.
