Ni-based super-alloy was synthesized by using conventional casting technique under vacuum and highly superheated treatment route . 3D-microstructural imaging map of the Ni-based super-alloy was constructed depending upon AFM-data evaluating that the morphology of the alloy-surface is a function of composition and preparation conditions .Furthermore raman spectra of casted Ni-based super-alloy was performed to confirm existence of different phases recorded via SEM and EDX-elemental analysis with their corresponding different vibrational modes such as Ni-O vibrating modes in the region 360-510 cm-1 and Ti-O vibrating mode which lie at 451,701 and 920 cm-1 respectively . A visualized study was made to prove existence of Ni- Ti-O mixed oxides with the ABX3 structure type .
