STUDY OF SIZE EFFECT IN FINE BERYLLIUM WIRE PHASE II,

Abstract

The 0.0046-in. diameter, as-drawn, beryllium wire can be chemical-milled to sizes near 0.0010in. diameter which show dimensional uniformity and good surface quality. A continuous trend toward higher strength with decreasing diameter of the wire was noted, and it appears possible that ultrafine wire with strength approaching the 200,000 psi level can be produced with consistency. A good degree of ductility was noted in wire chemical-milled below 0.0025-in. diameter as evident in necking of specimens; although, this ductility did not appear in tensile elongation values. Fract/re strengths in wire showing ductile fractures reached values near 220,000 psi. (Author)
