BERYLLIUM CASTING

Abstract

Methods were developed for the production of sound 3-in.-diam vacuum cast Be billets 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. The thermal gradient casting technique was reliable and reproducible. Ingots showed no indication of cracking as determined by radiographic tests and sectioning. Flat Be slabs have also been cast using this technique, and are being evaluat being evaluated. (Author)
