Abstract:

Work was continued on the chemical etchi g of rawn Be wires to reduc their diameters from 0.0047 to about 0.001 inch. Several matrix alloys were prepared by atomizing. These were prepared by first melting 2S Al in a crucible, adding the alloying el ments to the melt, and disintegra ing the molten stream of metal of about 100 psi pressure of dry compresse air. The powders thus collected were sieved through a 60 mesh screen and compacted in a 1-inc die. In the work on Be fiber composites, the spread in the size of the fibers was so great that it was difficult to designate an average size. T e e fibers w re mixed with plain 2S Al powder -60 mesh, compacted in a 1-inch die at 15 tsi and extruded at temperatures below 870F at an extrusion ratio of about 401. The tensile properties and elastic mo ulus were measured on a Hounsfield Ten ometer. It was a chief objective of this series of experiments to see if these composites could be densified by xtrusion technique , and it appears that this technique is satisfactory. Author
