Abstract


In this study, Al2O3 particles with an average size of 6 μm were reinforced with 15% by weight of 7039 Al alloy matrix by Vortex method and metal matrix composite sheet was obtained. Reinforced 7039 Al alloy and unreinforced 7039 Al alloy sheet were placed in specially prepared mold after surface cleaning. The metal matrix composites placed in the furnace together with the mold were kept in the oven at 630 °C for 30 minutes until approximately 30% liquid, 70% solid consistency. Immediately after applying pressure of approximately 7 MPa to the semi-solid composite material in the mold removed from the furnace, the mold was placed in the annealing furnace in the same manner and left at approximately 600 ° C for approximately 4 hours. The new layered composite material formed by the joining of the plates cooled in the kiln mold to 500 oC temperature was removed from the mold and cooled in water. The microstructure and mechanical properties of the composite material were determined by optical microscope, micro hardness and tensile tests.


Key words: 7039 Al alloy
