BERYLLIUM RESEARCH AND DEVELOPMENT IN THE AREA OF COMPOSITE MATERIALS. Period covered: June 15, 1958 to June 14, 1959
Ductility of some beryllium composite materials was compared with the ductility of beryllium itself. Bend ductility in sheet beryllium as a function of sample width and thickness revealed that grain orientation also played a part. Strip composites consisting of alternate strips of beryllium and aluminum or silver filler metal were investigated. Clad composites did not institute unusual changes in the composites' ductility. However. cladding appeared significant as a "fail-safe" and surface-protection medium. Beryllium may be clad by rolling or extrusion when a thin silver interlayer is present between core and cladding. Silver or aluminum coating did not change unusually the tensile strength or ductility of beryllium composites. Methods for polishing beryllium surfaces are described. (auth)
