In this paper, the effect of heating rate was investigated on the densification and mechanical properties of Ni–19at %Cr binary alloy developed by spark plasma sintering technique. The sintered binary alloy at different heating rate was prepared metallurgically for microstructural analysis, nanoindentation, and X-ray diffraction (XRD) analysis. Nanoindentation technique at room temperature was utilized in investigating the elastic modulus, and hardness of the alloys. However, nanoindentation tests showed that the maximum indentation hardness was obtained by the alloy sintered at heating rate of 100 °C/min, the hardness value and density were observed to decreases as the heating rate increases beyond 100 °C/min. Similar trend was observed for the relative density of the alloys, with the relative density decreasing as heating rate increases beyond 100 °C/min. The fractography analysis of the sintered alloy at different heating rate was characterized by ductile deformation mode. |
