Effect of holding temperature on semisolid microstructure of Mg2Si/Al composite

The effect of Bi addition on the microstructure and tensile properties of cast Al‐15%Mg2Si composite

“…In fact, since the cooling rate in this work is high, a dendritic morphology of eutectic particles is expected. A similar dendritic morphology of Mg 2 Si in unmodified Al-Mg 2 Si composite has been reported by other researchers [11,9]. After 0.03 wt.% Bi addition, primary Mg 2 Si has been found to be fully polyhedral and its size decreased to 20 lm, Fig.…”

“…Particulate metal matrix composites (PMMCs) are one type of metal matrix composites which have attracted attention due to their inherent isotropic properties, ease of manfacture and lower cast of production [8,9]. Among the numerous methods for production of particulate metal matrix composites, in-situ processes exhibits good particle wetting, even distibution of the reinforcing phase and thermodynamically stable systems [2,7].…”

3-D morphology and growth mechanism of primary Al6Mn intermetallic compound in directionally solidified Al-3at.%Mn alloy

“…The emergence of {100} planes in Fig. 2(a) and (e) may also be resulted from the poisoning effect of impurities in specimens, the enrichment of impurities on some {100} planes inhibit the growth of these planes in h100i directions, thus {100} planes partly or completely replace {110} planes, exhibiting cuboid and truncated bipyramid shape [8,33].…”

Formulation of the Effect of Different Alloying Elements on the Tensile Strength of the in situ Al-Mg2Si Composites

“…The Mg2Si intermetallic compound exhibits high melting point, low density, high hardness, low thermal expansion coefficient and reasonably high elastic modulus. The presence of Mg and silicon (Si) particles in the composite matrix with different alloying elements is considered to obtain the appropriate strength values and mechanical properties [6][7][8]. Additionally, the mechanical behaviors of the composites reinforced with particles were found to be a function of the matrix structure, addition alloying element, the volume fraction, particle size and shape of reinforcement [9].…”
