Probing the growth and melting pathways of a decagonal quasicrystal in real-time

Insung Han, Xianghui Xiao & Ashwin J. Shahani
This data was collected to study the principles of the growth and melting of a decagonal quasicrystal from a liquid. The composition of imaged sample is Al-9.55at%Ni-9.55at%Co, and the growth and melting of a decagonal quasicrystal were observed during the continuous slow cooling. The quasicrystalline phase shows weaker projection intensity because of more X-ray absorption resulting from its heavy elemental (Ni and Co) composition. This contrast difference allowed us to segment the quasicrystal from the...
