Collisions in outer space produced an icosahedral phase in the Khatyrka meteorite never observed previously in the laboratory
We report the first occurrence of an icosahedral quasicrystal with composition Al(62.0(8))Cu(31.2(8))Fe(6.8(4)), outside the measured equilibrium stability field at standard pressure of the previously reported Al-Cu-Fe quasicrystal (Al(x)Cu(y)Fe(z), with x between 61 and 64, y between 24 and 26, z b...
