Abstract: The microstructure control technique and mechanical properties of particle or randomly oriented fiber reinforced metal matrix composites fabricated by LPI process were examined. SiC particles and fibers were used as reinforcement, while Al-4mass%Cu alloy, Al-7mass%Si alloy and AZ91 alloy were used as matrix. A mixture consisting of aluminum particles and reinforcements was prepared as a preform to control the distribution of SiC particles and fibers in MMCs. MMC specimens were fabricated by infiltrating the molten matrix alloy into the preform by pressing the melt surface with a low pressure of Ar gas. MMC specimens showed high performance in thermal cycling test as well as an excellent wear resistance. Vickers hardness of FRMMC specimens was almost constant on the different sections and the physical and mechanical properties were found to be isotropic.
