Abstract : Single crystals of zone-refined Be were jacketed in mild steel tubing and were swaged at 450 C. Various intermediate anneals were employed. When the Be had been reduced to the desired diameter, swaging was stopped and the jacket was removed. The high-purity Be wire was then deformed by standard Be wire-drawing techniques. Extensive longitudinal rupturing occurred during this operation and very poor yields were experienced. Even so, a fair amount of fabrication exerience was gained and some important metallurgical information was generated. (Author)
