原位研究了二十面体Al-Pd-Mn准晶单晶粒在800 °C退火过程中孔隙率的演变。一个急剧收缩的孔隙观察和解释的框架中的空位介导的扩散模型。
The evolution of porosity in an icosahedral Al-Pd-Mn quasicrystal single grain has been studied in situ during an annealing at 800 °C. A drastic shrinkage of pores was observed and interpreted in the frame of a vacancy-mediated diffusion model.
