Abstract

The composites of 6061 and 2014 aluminum alloys reinforced with alumina particles have been subjected to solutionizing treatment at 540 °C for various lengths of time up to 20 hours. The two composites show different behavior when the hardness is measured as a function of solutionizing time. The 6061 aluminum alloy containing 0.1, 0.15 and 0.2 volume fractions of alumina (VFAP) show a continuous increase in hardness values as a function of solutionizing time while 2014 alloy shows softening under almost identical experimental conditions. The grain growth law has been found to be observed in both composites and their monoliths. The aging behavior as influenced by the solutionizing seems to be affected by the solutionizing time in an identical fashion. Even though the monoliths indicate a decrease in time required to get the peak hardness (TPH) values the composites show an initial decrease and then increase in TPH values at 200 °C as a function of solutionizing time. The bonding between the particles and the matrix in the two composites has been found to improve as a result of longer solutionizing time as can be seen by the SEM fractographs for the samples deformed to fracture during room temperature tensile testing.
