Conclusions
-
1.
A physicochemical mechanism of modification of hypoeutectic and hypereutectic Al−Si alloys based on the concept of the structure of the outermost unfilled electron shells of the atoms is suggested. Experimental results that substantiate this mechanism are presented.
-
2.
Further study of the suggested mechanism will show new possibilities for improving the modifying technology of these alloys.
