Zusammenfassung:	The Be-Si system was examined in an effort to clarify the question as to whether any degree of solid solution is produced by splat cooling. Alloys of composition 40, 60, and 75 w/o Be were prepared and quenched. The X-ray patterns of these alloys, both before and after quenching, showed no significant changes of spacings from those for pure Si. It appears, therefore, that no change due to rapid quenching occurs in the Be-Si system. In the Be-Cu system, an additional composition (namely 40 w/o Be) representing the eutectic between Be and the delta phase was prepared and quenched. The reflections of Be and of the delta phase were identified on the X-ray patterns before and after quenching, and no shift in the spacings of either was found. Further effort was devoted to the problem of the Be21Ni5 pattern.
