🧪 Eutectic Phase Diagram: Binary Alloy Solidification

Interactive 3D phase diagram paired with an alloy melt where you adjust composition and cooling rate to watch a two-metal mixture solidify along the liquidus and eutectic lines.

Chemistry & Materials3DModerate60 FPS

A 3D binary phase diagram sits beside a molten crucible: adjust the composition and cooling rate to watch dendrites form on the liquidus line and the remaining melt freeze into lamellar eutectic bands.

🔬 What It Demonstrates

Off-eutectic alloys cross the liquidus and grow primary dendrites of the majority metal while the leftover liquid drifts toward the eutectic composition; at the eutectic point, alloys of any starting mix freeze in one step into alternating solid layers.

🎮 How to Use

Set the melt's composition and cooling rate, then let cooling run. Watch the marker slide down the liquidus toward the eutectic point while atoms in the crucible lock into dendrites and lamellae. Reheat to try another mix.

💡 Did You Know?

Eutectic alloys such as solder and many casting aluminium alloys are chosen precisely because their single, sharp freezing point gives predictable, fine-grained castings instead of a mushy, slow-freezing range.
