Abstract
The Debye-Scherrer method has been used to study the sequence of precipitation structures in a two percent beryllium-copper alloy. A special x-ray camera fitted with a furnace was used to follow the age-hardening process at controlled elevated temperatures. It is concluded that no intermediate structure exists which is capable of three dimensional diffraction. Two earlier investigations of this system suggest the existence of intermediate structures. It is shown in this paper that these intermediate structures are actually oxides of beryllium-copper. Existing confusion regarding the correct lattice parameters of the alpha and beta prime phases has been eliminated with the determination of their precise values.
