TEM study of impurity segregations in beryllium pebbles

“…The former results suggest that the precipitates in beryllium are single phase particles [12]. The detailed analytical investigation of individual particles shows that they usually contain of several beryllide intermetallic phases (Fig.…”

“…In several research studies the presence of impurity particles in beryllium is mentioned without further analytical characterization [9,10]. At the same time it is well known that mechanical properties of Be are influenced by impurity content [12,13]. Significant degradation of mechanical properties was observed in irradiated Be.…”

Precipitation Characteristics of Rocky Flats Beryllium Ingot Sheet.

“…The Be foils for electron-transmission microscopy were thinned in a Glenn-Dual-Jet thinning unit. 3 The electrolyte consisted of 400 milliliters (ml) of ethylene glycol, 40 ml of nitric acid (HN0 3 ), 8 ml'of sulfuric acid (H 2 S0 4 ), and 8 ml of hydrochloric acid (HCl). About 900 milliamperes of current at 36 volts were used.…”
