The powder mass is formed at different temperature, i.e., 120 �C and 180 �C applying 130 kN axial loading simultaneously from top and bottom punches.

The final products were characterized through density measurement, hardness test, and three point bending test whereas the microstructures were analyzed by Scanning Electron Microscopy (SEM). The results revealed that the properties of sintered parts formed at 180 �C are better than those formed at 120 C. The suitable forming parameters and sintering schedules were identified from this study.
