XD(TM) Reinforced Beryllium-Based Composites

Abstract

Eleven beryllium castings were made by Brush Wellman using dispersoid materials provided by Martin Marietta Laboratories. Eight castings had a beryllium matrix, while three had a NiBe matrix. Each casting was analyzed metallographically. It was found that all the selected dispersoid materials reacted with the beryllium matrix. Little grain refinement was observed in the castings. Slabs cut from the cast billets were rolled to Produce sheet. It was found that the grain size of the rolled material was slightly finer than a pure Be control sample.
