Abstract

In this study, producibilify of B4C particle reinforced Ad alloy matrix composites from 7075 Al alloy machining chips has been investigated. After blending 7075 Al alloy with 10 wt % B4C particles, mixtures were pressed at 350 degrees C for two hours under a pressure of 625 MPa. Characterization of the composites was made by structural examinations and mechanical tests (hardness and dry sliding wear tests). When compared to conventionally extruded 7075 Al alloy, 10 wt.% B4C particles reinforced 7075 aluminum alloy matrix composite exhibited superior hardness and wear resistance especially after T6 tempering.
