Abstract
The vapor pressure of magnesium and its alloys containing beryllium was measured by transportation method in temperature range of 700-850°C, and the vaporization rate of magnesium under vacuum condition through oxide film was studied at the temperature of 550-600°C.
The protective film containing beryllium oxide which showed protective behaviour on oxidation of magnesium alloys (see the previous report) suppresses the vaporization of magnesium under the temperature of below 600°C.
In molten magnesium alloys containing beryllium, the relationship between decrease in vapor pressure and behaviour protecting from burning could not be found clearly.
