Including: Hypo-eutectic, Hypereutectic, Hyper-eutectic, Hypoeutectic Alloy, Hypo-eutectic Alloy, Hypereutectic Alloy Hyper-eutectic Alloy
If an alloy is not of eutectic composition then it is either hypereutectic or hypoeutectic. If the alloys' composition places it to the left of the eutectic point on a phase diagram, then it is hypoeutectic. If it is to the right of the eutectic point then it is called hypereutectic. Note, though, that the phase diagram must have a eutectic point to have hypoeutectic or hypereutectic alloys.
