Özet

Self-propagating high temperature synthesis processes are one of the highly productive and economically reasonable methods for the metallurgy industry. The synthesis of compounds by self-propagating high temperature takes place as a combustion reaction of reactive raw materials and the following chemical reaction by heat transfer that allows an easy production of ceramic and intermetallic materials. In this study, the refinement of nickel-based SHS alloys were carried out by remelting of the alloys via mini vacuum arc melting system. The changing in the microstructural and mechanical properties and chemical compositions of the obtained SHS alloys were investigated by remelting process under argon atmosphere. The obtained product samples were characterized by wet chemical analysis, Vickers microhardness and Scanning Electron Microscope (SEM) techniques.
