| Popis: | Aluminum matrix composites are emerging as advance engineering materials due to its high specific strength and stiffness, good wear resistance and high temperature properties. Properties of Al reinforced with Al 2 O 3 and SiC are widely investigated. In the present study, mechanical properties of B 4 C reinforced Al matrix is investigated due to higher hardness and lower density properties than SiC and Al 2 O 3 . The high temperature deformation behavior of 5, 10, 15 and 20 wt% B 4 C powder having an average particle diameter of about 10 μm aluminum matrix composite sintered at 650 °C was investigated by creep tests at temperatures ranging from 400 to 450 °C and creep resistance of Al alloy is enhanced by the presence of B 4 C particles. Measurement of impact and hardness properties of composites showed that impact values decrease and hardness values increased with increase in weight fraction of reinforcement. |
