摘要：

In the present study, magnesium and magnesium matrix composites reinforced with 10, 20 and 30 wt% B4C particulates were fabricated by powder metallurgy using hot pressing technique. The microstructure, mechanical properties and wear behaviour of the samples were investigated. Microstructure characterization showed generally uniform distribution of B4C particulates. XRD investigations revealed the presence of Mg, B4C and MgO phases. The mechanical properties of the investigated samples were determined by hardness and compression tests. Hardness and compressive yield strength significantly increased with increasing B4C content. The reciprocating wear tests was applied under loads of 5, 10 and 20 N. Wear volume losses decreased with increasing B4C content. Abrasive and oxidative wear mechanisms were observed.
