uring the past decade, considerable research effort has
been directed towards the development of in-situ metal
matrix composites (MMCs), especially in Magnesium Metal
Matrix Composites in which the reinforcements are formed
in-situ by exothermal reactions between elements or between
elements and compounds. SiC can be used as a reinforcement
which takes part in in-situ reaction with Magnesium. The
main objective of this experiment was to produce magnesium
silicide (Mg
2
Si) since this gives better microstructural and
mechanical properties than the magnesium alloy itself. For
better results, SiC was heat treated at different temperatures
for a different amount of times to remove any contaminations
on the SiC particles and make the surface properly active.
SiC mixed with pure magnesium chips and magnesium alloy
blocks and heated in the furnace with argon gas to prevent
oxidation of the magnesium. Heating of the mixture was
done at different temperatures for different time periods.
Among the trials, pure Mg and Mg alloy combined with SiC
produced mentionable result at 900˚C for 1 hour time period.
