Abstract:

The chemical etching of 0.0047 inch beryllium wires seems to work satisfactorily. The time required for reduction in diameter from 0.0047 inch to 0.0010 inch was f the order of 1.5 minutes. The wires reduced to 0.002 inch diameter could be handled fairly easily. However, the 0.001 inch wires were extremely fragile. The work on Be-Ag composites was continued. In view of previous difficulties, some experiments were performed on Be-Ag composites without aluminum or germanium. The work on the silver-aluminum alloys indicated that the matrix was relatively weak with tensile strengths no greater than about 60,000 psi. A number of prealloyed aluminum alloy powders were prepared by atomization from a melt. These powders were compacted and extruded at 800-900 F with a 161 extrusion ratio. The results of yield strength, tensile strength and elongation are summarized. Author
