Mg1-xZnxAl2O4(x=0～1)尖晶石的离子束辐照效应研究
Ion irradiation effects of Mg1-xZnxAl2O4(x=0-1)spinels
摘要
Abstract
Spinels have been proposed for a multitude of nuclear-energy-related applications,including as nuclear waste forms,inert matrix fuels and structure materials for nuclear reactor,due to its excellent mechanical properties,chemical durability and radiation resistance.The study of radiation behavior and radiation tolerance have important significance in materials selection,assessment and modification.The 500 keV He ions irradiation were performed on Mg1-xZnxAl2O4(x=0-1)spinels at room temperature with different ion fluence.There were a phase transition from order spinel to disorder spinel(O-D)but no amorphization in all of the samples even if the highest ion fluence1×10 17 ions/cm2 according to the results of grazing incidence X-ray diffraction and Raman scattering spectrum(Raman).The swelling ratio of MgAl2O4,Mg0.4Zn0.6Al2O4 and ZnAl2O4 caused by irradiation is 0.43％,0.12％and 0.67％,respectively.We think Mg0.4Zn0.6Al2O4 spinel have the best radiation swelling tolerance,closely followed by MgAl2O4 and ZnAl2O4 is the worst when the ion fluenceis below 1×10 17 ions/cm2.But,maybe the swelling ratio of Mg0.4Zn0.6Al2O4 will outstrip MgAl2O4 at the higher ion fluence than 1×10 17 ions/cm2.关键词
