title = "The effect of heat treatment on the properties of friction stir processed AA7075-O with and without nano alumina additions",
abstract = "In this study, four passes friction stir processing (FSP) were applied on AA7075-O with and without the incorporation of alumina nano-particles (Al2O3) of average size 40nm. FSP parameters were constant at 500rpm and 40mm/min speed with tilt angle of 3. FSP rotation direction applied on clockwise and then counters clockwise direction every two passes. The friction stir processed (FSPed) materials were section and solution treated at 515°C for 1.5hrs that followed by age hardening at 120°C for 12, 24 and 36hrs. The effect of heat treatment regimes on the microstructure and hardness were examined. The microstructure and hardness after HT were compared with that of as FSPed material in each case. It has been found that in case of as FSPed material without any HT the effect of nano-alumina particles is significant in hardness increase relative to the one without powder. However, applying heat treatment regime has resulted in a slighter difference in the hardness between the two cases with and without nano particles additions.",
