This data was collected to study the growth and relaxation dynamics of an icosahedral quasicrystal from a liquid. The composition of the imaged QC is Al-19at%Pd-10at%Mn, and the growth and relaxation dynamics of an icosahedral quasicrystal were observed under slow cooling conditions. The quasicrystalline phase shows weaker projection intensity because of more X-ray absorption resulting from its heavy elemental (Pd and Mn) composition. This contrast difference allowed us to segment the quasicrystal from the liquid...
