Casting,thus concerned with techniques for casting beryllium and a review of current knowledge about the solidification behavior of the metal. Many factors such as mold design, heat transfer during solidification, and impurity control have a direct bearing on both the soundness and structuce of the ingot an

Plasma-Sprayed Beryllium,powder, usually followed by a densifying heat treatment, can produce high-strength material competitive in properties and cost with that made by any other route. In addition, it will be claimed that for large, thin-walled bodies this process is unmatched in economy of source material and expendable

Machining,ent status of be techniques is presented. A bibliography of reports on beryllium machining is included. The basic beryllium machining problems, namely, toxicity, tool life, and machining characteristics, are discussed, as is the way in which material source, product application, and economies may in

Joining I: Mechanical/Adhesive, candidate for reducing overall system weight. Even with the availability of the forthcoming Space Transport System (shuttle), weight savings will continue to be a very important parameter in spacecraft design. To achieve the full potential of beryllium, it is necessary to develop efficient methods
