FEA RESULTS OF NICKEL ALLOY
The total deformation, equivalent stress analysis, equivalent strain analysis for the Nickel alloy is shown in figure 17, 18, and 19 respectively. The total heat flux and directional heat flux analysis for the Nickel alloy is shown in figure 20 and 21 respectively. The same procedure was followed for the static structural analysis and the thermal analysis of the Nickel alloy as like the structural steel and Titanium alloy. The same constraint and rotational velocity is considered.

The above shown graphs clearly show the comparison among the structural properties between the three materials. Out of the three materials Titanium seems to undergo more deformation compared to Nickel alloy and Structural steel. The above shown graphs clearly shows the comparison among the thermal properties of the three materials. The directional heat flux for Nickel alloy is the highest among the three materials but since the total heat flux is least for Nickel alloy when compared to Titanium alloy and Structural Steel.
The analysis was carried out for the impeller of the turbocharger using ANSYS.In the analysis part the model of the impeller was created using CREO and the files were saved in STEP format and imported to ANSYS. The analysis is carried out on the redesigned model with different materials (Structural Steel, Nickel alloy and Titanium alloy) and the results were compared. From the above result summary table we conclude that Nickel alloy was found better than Structural Steel and Titanium alloy. From the above data we observed that minimum stress and
deformation is obtained for Nickel alloy. Also the total thermal flux induced on the impeller was low for the material Nickel alloy. Thus the impeller could withstand more stress and temperature if Nickel alloy is used. So we conclude that Nickel alloy is the most apt material among the three chosen materials for the impeller of the
