Methods were developed for the production of sound three-inch diameter vacuum-cast beryllium billets suitable for fabrication. The casting technique relies on a thermal gradient within the mold (hot top, cold bottom) to control directional solidification of the metal and eliminate the centerline shrinkage encountered in conventionally cast billets. The thermal gradient casting technique has been found to be reliable and reproducible. Ingots produced by this process show no indication of cracking as determined by radiographic tests and sectioning. Flat beryllium slabs have also been cast using this technique, and these are now being evaluated for soundness. (auth)
