The Lattice Dance
The atomic choreography of Martensite and Austenite phases.
- Atomic Blueprint
Solid-State Metamorphosis
Nitinol doesn't melt to change; it undergoes a solid-state phase transformation. Its atoms rearrange into new patterns without ever losing their bonds.
- The High Phase
Enter Austenite
At high temperatures, Nitinol assumes its 'parent' phase called Austenite. This structure is a rigid, cubic lattice that represents the metal's memory.
- Structural Symmetry
The Cubic Ideal
In the Austenite phase, atoms are perfectly aligned in a highly symmetric grid. This is the material's most stable, energetic state.
