Abstract

The recrystallization behavior of beryllium containing fine BeO dispersions has been studied by following the changes of hardness during annealing and the modifications of the microstructure by optical and transmission electron microscopy. It was found that for equal concentrations of BeO the recrystallization temperature was dependent upon the size of the dispersoid, being higher the finer the median particle size of the oxide. In an alloy with a median size of 600Å a dislocation substructure was maintained up to very near the melting point of beryllium.
