In metallurgy, describing an alloy composition that is slightly richer in one component than the eutectic composition, positioned just before the eutectic point.
From Greek 'anchi-' (near, almost) + 'eutectic' (from Greek eutēktos, easily melted). The prefix literally means 'near the eutectic,' describing alloys positioned near but not at the eutectic composition.
Metallurgists use this term to describe alloys that are tantalizingly close to the 'sweet spot' where metals melt most easily—like being almost-but-not-quite at the perfect temperature for the smoothest melting.
