“…Zhou and Xu [10] in their work reported that the particle can be assumed to act as a barrier to the dendritic growth. Kaur and Pandey [20] pointed out the existence of dendritic morphology in a reinforced alloy used in present study. It is also reported in another work that the growing dendrite tip realizes the existence of a hot liquid front near the particle as thermal conductivity of particle is low, which in turn retards its further growth [21].…”

The present investigations are a comparative study of single and dual reinforcement particles on microstructural features and wear behavior in LM-13 aluminum-silicon alloy. Silicon carbide and zircon sand particles of 20-32 lm are reinforced in the alloy by two-step stir casting method. Wear study reveals that the dual particle reinforcement enhances the wear resistance as compared to single particle reinforcement if mixed in a definite proportion. Study also indicate that a combination of 15 % reinforcement of zircon sand and silicon carbide particles in the ratio of 1:3 into the composite exhibits better wear resistance as compared to other combination.

“…Silicon morphology is modified also by introducing of zircon sand particles to Al alloy. Kaur and Pandey (2010) have reported that zircon sand particles provide nucleation site for solidification of Si and changes the morphology of silicon particles from long thin needle shape to globular. In fact, the localized cooling effect produced by zircon sand particle around its vicinity led to such type of morphological changes.…”

This paper presents the results of experimental investigation on microstructure (size and morphology of eutectic Si), impact toughness and sliding wear properties of A356 Al-Si alloy and composites containing 10, 20 and 25 wt% of SiCp reinforcement produced by semisolid stirring technique. The results revealed that an increase in SiCp content leads to a reduction in the size of eutectic Si and also changes its morphology from plate-like to equiaxed. Furthermore, addition of 10 and 20 wt% silicon carbide reinforcement decreased the impact toughness by 6 and 18%, respectively. A356/25wt%SiCp composite registered the lowest impact toughness with reduction of 33% due to debonding and agglomeration of SiCp in the matrix. The sliding wear results showed that the wear resistance of the composites was significantly higher than that of the matrix alloy due to the increase in hardness as well as reduction in the size and also morphology transformation of eutectic silicon with increase in SiCp content. However, the existence of particle-porosity clustering with increasing the SiCp content to 25 wt% played a significant role in deteriorating the wear behavior of the composite.

“…The variation in porosity level depends on the melt percentage variation in the spray [8]. In the initial stage of rolling (i.e about 20 % thickness reductions), the metal flow in the Al-Si deposit is mainly in the thickness and as well length direction resulting in the removal of porosity by rearrangement and restacking of spray deposited particles.…”

Al-6%Si alloys were prepared by spray deposition technique and then cold rolled to various thickness reduction. Hardness, porosity and microstructural characteristics of the alloy were studied from top to centre and from centre to periphery of the deposit for different percentage of thickness reduction. Hardness was found to increase and porosity was observed to decrease with the increase in percentage of thickness reduction. Aluminum grains were observed to be elongated in the rolling direction after 80 % thickness reduction.
