| Abstract | ||
| The influence of Titanium (Ti) & Carbon (C), as gray cast iron master alloy, additions on the structure modification efficiency of the phosphorous (P) in near eutectic Al–14Si alloy and the nucleating mechanism was studied in this work. The results show that the phosphorous modification efficiency can be significantly affected by this addition and the sizes of the primary Si particles can be obviously refined after the addition of trace Ti&C. Micro probe Analyzer (MPA) shows there is a coupling of aluminium phosphides (AlP) and Al4C3 particles in the center of primary Si. Moreover, the nucleation mechanism of primary Si by like-peritectic coupling of AlP and Al4C3 was presented. The formation mechanism of like-peritectic coupling of these particles was also discussed. | ||
