From: Collisions in outer space produced an icosahedral phase in the Khatyrka meteorite never observed previously in the laboratory

Figure 3

Subsolidus projection of the ternary Al-Cu-Fe phase diagram in the vicinity of the icosahedral phase (modified after Bancel 12).

Shaded regions indicate pure phase fields and tie lines bound two-phase regions. The maximal extent of the icosahedral phase occurs within the boxed area labelled i-region. The dark shading shows the section of the i-region in which transformations have been identified. Empty red and light blue spheres correspond to data from i-phase I (icosahedrite) and i-phase II, respectively. Errors within the size of the symbols.
