Abstract Scope |
Functional materials such as nickel silicides (Ni2Si) are considered promising materials for building complex and strong structures. They have proven to have a high melting point, low electronic resistivity, excellent corrosion resistance, and be thermally stable, however, their overall performances are still challenging due to their brittleness. Therefore, it is essential to prepare high-strength nickel silicide-based materials to improve toughness. In the present work, arc melting has been utilized to synthesize carbon (C) alloyed nickel silicide (NiSi11Cx, x = 0.2, 1 wt%) with varying amounts of carbon with the aim of improving the microstructure and mechanical properties of the alloy. The produced NiSi11Cx alloys were characterized by Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS), X-Ray Diffraction (XRD), Differential Scanning Calorimetry (DSC), and microhardness tests. The influence of carbon content on the microstructure and mechanical properties of NiSi20Cx alloys are discussed in this paper. |
