These alloys exhibit excellent properties such as wear resistance, corrosion resistance, impact strength, hardness and ductility, which are highly dependent on their composition and production conditions. Despite the relatively low formation of oxide layers on the surface of nickel aluminum bronze components under heat treatment conditions due to the high nickel content, there are special applications where the formation of oxide layers on the surface is undesirable. For this reason, the heat treatment of CuAl10Ni5Fe3Mn alloy was carried out in a vacuum furnace and the heat treatment process conditions in a non-vacuum muffle furnace were compared. For comparison purposes, the microstructure of the materials was examined and hardness and tensile tests and potentiodynamic corrosion tests were performed. It was determined that heat treatment in the muffle furnace led to a decrease in the proportion of the α phase and a higher formation of the β and κ phases compared to the heat treatment in a vacuum atmosphere. The material heat treated in the muffle furnace exhibited higher hardness and strength values as well as improved corrosion resistance compared to the material treated in the vacuum furnace.}, number={1}, publisher={Tekirdağ Namık Kemal Üniversitesi}
