电子束辐照诱发纳米Al/Al_2O_3复合颗粒中Al非晶化的纳米束斑原位分析

IN SITU NANOBEAM STUDY OF ELECTRON BEAM IRRADIATION-INDUCED AMORPHIZATION OF Al PAR-TICLES ENCAPSULATED BY Al_2O_3 SHELL

在 ＨＦ－２０００场发射电镜上完成了Ａｌ／Ａｌ２Ｏ３颗粒的辐照诱发Ａｌ非晶化转变和原位观察。

Amorphization behavior of aluminum in the interface region of an ultrafine Al particle encapsulated by Al2O3 shell under the electron beam irradiation was achieved by HF-2000 field emission gun transmission electron microscope. Nanobeam X-ray energy dispersive spectrum analysis revealed that the mechanism of the amorphization is an oxidization behavior.
