BERYLLIUM RESEARCH AND DEVELOPMENT IN THE AREA OF COMPOSITE MATERIALS.
Abstract
The effect of sample width on bend ductility is given for one type of grain-oriented beryllium, for which tensile properties are known. Bend ductility dropped off sharply as relatively narrow widths of the order of 1/4 - 3/8 inch were exceeded. Composites consisting of alternate strips of beryllium and aluminum in single layer were formed by aluminum-silicon brazing. An effort was made to determine the dependence of bend ductility, around a 0.200-inch radius, on width of aluminum filler strip. Bend ductility was compared to (1) that of the individual beryllium strip, and (2) that of a beryllium sheet having width equivalent to the sum of beryllium strip widths in the composite. The magnitude of bend ductility in the composite was found to be intermediate between (1) and (2) above. Several Samples braze clad with 316 stainless steel were subjected to bend tests, as were several strip samples of various widths which were coated with Al-Si braze metal.
