The beryllides, being intermetaUic compounds, are hard, strong materials which exhibit Httie ductihty at room temperature. Strength properties increase gradually as a function of temperature up to about 870°C, above which a sharp increase in strength occurs, peaking in the region of 1260°C the modulus of mpture values exceed 280 MPa (40,000 psi) at this latter temperature. [Pg.76]

The beryllides continue to be of interest for high temperature aerospace applications because of their oxidation resistance, low density, and high strength at elevated temperature (7). The limited strain capacity of the materials, particulady at low temperatures, has thus far prevented actual use. [Pg.76]

Neptunium is fairly reactive and forms some interesting compounds. Examples include neptunium dialuminide (NpAl2) and neptunium beryllide (NpBc3). These compounds are unusual because they consist of two metals joined to each other. Normally, two metals do not react with each other very easily. Neptunium also forms a number of more traditional compounds, such as neptunium dioxide (Np02), neptunium trifluoride (Npp3), and neptunium nitrite (NPNO2). [Pg.371]

Beryllides and Borides. CrBe2 and CrBj have been prepared by the reactive hot-pressing method and studied by X-ray diffraction. The crystal structure of the interstitial boride, CrB j, has been determined. The results suggest that the Cr atom occupies a high symmetry position.The ternary complex boride UCrB has been shown by two independent crystallographic studies to have the YCrB -type structure. ... [Pg.96]
