Magnesium-tin based composites processed through stir casting
2017
The present work confers to the fabrication and characterization of two Mg-alloys (Mg-8%Sn and Mg-8%Sn-3%Al-1%Si (TAS831)). SiC particulates having
average particle size of 25-125 µm were introduced as the reinforcement in Mg-8%Sn
and TAS831. Castings of both Mg-8%Sn and TAS831 alloys composite (base alloy
reinforced with silicon carbide particulates) were produced using stir casting technique.
A thorough investigation was carried out by metallography, hardness measurement, and
X-ray diffraction technique. SiC particulates were uniformly distributed throughout the
matrix. The hardness values of the composites material increases significantly as
compared to the unreinforced counterpart.
