Abstract: In this investigation, AA6061 milled particle size was fabricated by milling machine plus compacted by hydraulic press in room temperature. Finally, sintering in the temperature range of 478-617 OC. Four groups of particle size were chosen (25, 63, 100, mix) µm. Each group has compacted by three specimens for various of Sintering temperature (487, 552, 617) OC, the compaction pressure and holding time were constant (9) tons, (20) min respectively. The physical properties of the four groups depend on the variations of sintering temperature. So, it is useful first to present and discuss the results of microstructure to understand the physical properties. In this study, the density value was increased with the increasing of sintering temperature value to (552) OC of all types of suggested groups due to the bonding between particles was stronger, in addition, the pores amount was decreased. After that, it was decreased due to the particles become big size lead to the barriers were decreased. The maximum value of density was detected by mix group which was (2.601 gm/cm3) while the particle size (25) µm was the minimum value which was (2.494 gm/cm3). Whereas the groups (63) µm and (100) µm were (2.590 gm/cm3) and (2.593 gm/cm3) respectively.
