Abstract

Quasicrystals (QCs) are unique materials, whose crystallographic identity has been controversial for many years. Using recent advances in shock synthesis, Hu [(2020), , , 434-444] reproduce for the first time the formation conditions of the icosahedral AlCuFe QC (i-phase II) found in the Khatyrka meteorite. The authors demonstrate that shock-recovery experiments provide a novel strategy for preparing and exploring QCs.

摘要

准晶体（QCs）是独特的材料，其晶体学特性多年来一直存在争议。利用冲击合成方面的最新进展，胡[（2020年），，，434 - 444]首次重现了在哈泰尔卡陨石中发现的二十面体AlCuFe准晶体（i - 相II）的形成条件。作者证明了冲击恢复实验为制备和探索准晶体提供了一种新策略。
