Abstract
Remarkable nanoscopic changes were observed in-situ in metastable oxide particles on the room temperature stage of a TEM under as electron beam intensity of 1019 e/cm2sec. Particles of 10-15 nm diameter α-Al2O3 and 5nm diameter Al metal were obtained from 100nm metastable θ-Al2O3 particles by a process dependent on the electron beam intensity. Al nanoparticles were bonded by continuous irradiation via surface diffusion of Al atom and the formation of 2 nm sized Al clusters The effects of the electron beam are the irradiation induced increase of the oxygen mobility and localized heating.
