Initial investigations were conducted on NbBe/sub 12/, Nb/sub 2/Be/sub 17/, and Nb/sub 2/Be/sub 19/. These compounds were first prepared by reacting the metal powders, then analyzed and used in the fabrication studies. Sintering studies were conducted on cold-pressed specimens of the niobium beryllides to evaluate the variables of sintering temperature, cold-compacting pressure, binder bake-out, and mesh size. Hot-pressed specimens of these materials were prepared for the metallurgical processing phase. Some of the variables studied were jacketing material, handling technique, and preliminary upsetting procedure. A 500-lb impact tester was constructed for the upsetting study. (auth)
