For this study, 0-4 % (in wt.) Al4C3 particles were added to AA2014 powders and pressed under 660 MPa pressure at 200 degrees C. Compacted powder pellets were sintered at 580 degrees C under Argon gas atmosphere for 60 minutes. The sintered specimens were solved at 510 degrees C for 420 minutes and quenched to obtain a supersaturated solution. In order to determine the optimum ageing time at 190 degrees C, the ageing process was applied at different times. After heat treatments, it was aimed to find out the ageing conditions with the help of scanning electron microscopy images and macro- and micro-hardness studies. It was found that the average ageing time for the specimens was 400-450 minutes.
