... temperature is in accord with the currently accepted value, the eutectic composition was later changed to 12.2 ± 0.1 at.% Si ( Ref 7 , 8 , 9 ). The initial error in establishing the eutectic point is due to the fact that the temperature of formation of the primary constituents (aluminum and silicon...

This is the eutectic point (e), which defines an alloy composition that has the lowest melting point of the A-B system, hence the name...
