Ductility in Beryllium Related to Grain Orientation and Grain Size
- Nuclear Metals, Inc., Cambridge, MA (United States)
The anisotropy of fracture and slip, i.e., the brittleness and ductility of the beryllium single crystal, is characteristic also of polycrystalline beryllium in which the Brains are oriented in a preferred manner. Beryllium with grain orientations resulting from hot working either uni-directionally or bi- directionally is ductile or brittle in directions given by the anisotropy and orientation of the grains. Textures developed from various hot-working sequences are given, and tensile results are correlated with textures. Not only texture but fine grain size ls necessary for obtaining high tensile elongation. Ultimate tensile strength and elongation are-both correlated with grain diameter. Of particular interest is the case in which unusually high tensile elongations of 30 to 40% are obtained when basal planes are oriented to carry little or no tensile stress.
