Synthesis - Opis:
- The synthesized Ni-alloy was prepared via conventional casting technique under vacuum and highly superheated treatment route. The casting parameters such as solidification cooling rate (SCR) was monitoring by both of AFM and SEM .Micro-structural investigations within different spots in the same sample indicated that γ matrix is the domain phase besides minor phases as MC carbides, σ phase and η phase which was observed to solidify in two forms as plate-like and blocky shape. The volume fraction (Vf) of σ and η phases was increased as the solidification cooling rate decreases. 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 casting parameters .Furthermore raman spectra of highly superheated 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 Mo-O vibrating mode which lies at 1005 cm-1.
