Quick Hypoeutectic - an alloy to the left of the eutectic composition, but to the right of the point where the solvus and solidus lines corresponding to the left composition meet, as shown below.
Hypereutectic - an alloy to the right of the eutectic composition, but to the left of the point where the solvus and solidus lines corresponding to the right composition meet, as shown below.
Schematic
This eutectic diagram indicates that an alloy that falls within the hypoeutectic region is hypoeutectic and that an alloy that falls within the hypereutectic region is hypereutectic.
