Effect of self-doping of Be into Gd2O3 oxide film on incombustibility of Mg-Zn-Gd alloy
Source abstract
Abstract
Non-flammable Mg-Zn-Gd alloys were developed by small addition of Be. The Mg 97Zn 1Gd 2 (at%) alloy exhibits relatively low ignition temperature of ∼1020 K due to the formation of non-uniform and less protective Gd 2O 3 surface films, whereas Be-containing Mg-Zn-Gd alloys show high ignition temperature of more than 1200 K. Soft X-ray emission spectroscopy (SXES) revealed that Be was concentrated as metallic and oxide states in the Gd 2O 3 surface film on the oxidized Mg 96.9Zn 1Gd 2Be 0.1 alloys. The segregation of Be along the Gd 2O 3 grain boundaries prevents the inward diffusion of oxygen resulting in forming a thin and uniform Gd 2O 3 film.
