Abstract

In this investigation, AA6061 milled particle size was fabricated by milling machine and later compacted by hydraulic press in room temperature. Seven specimens were chosen for the heat treatment process. For reference, one specimen was treated solely by the quenching and another one was treated by the aging only, On top of that, there were five specimens were subjected to various holding times during the aging. The experimental results show that the maximum value of compression strength was 300.47 MPa for the specimen subjected to quenching and aging of holding time 4 hours and the maximum value for microhardness was 100.44 Hv for the same specimen. While the density value was decreased with increasing the holding time. The maximum value of the density was 2.61 g/cm3 for the specimen (Quenching only). X-ray inspection was detected some of chemical compound were created such as (Al86Fe14) and (Cr13Ni5Si2).
