An evaluation was completed on the effect of pouring temperature and mold temperature on Be grain size. The results show a typical relationship of mold temperature and grain size with higher mold temperatures prcducing larger columnar grain diameters. Higher pouring temperatures produced smaller as-cast columnar grain diameters. No explanation is offered for this result. Small additions of Ge, La, and Zr were utilized as potential grain refining additions. Some columnar grain size reduction was accomplished but optimum amounts were not determined.
