Abstract

The aim of this research is studying some physical properties (bulk density,
apparent density, apparent porosity percentage, water absorption percentage) for
metal matrix composite material. Aluminum matrix consists boron carbide particles
as a reinforced phase. Different percents (0%, 2%, 5%, 10%, and 15%) of (B4C)
have been used. powder technology process is used for preparing the specimens,
the results shows that the bulk and apparent density decrease, apparent porosity
percentage and water absorption percentage were increasing as percentage of (B4C)
particles increase.
