    Abstract

    The tensile, compressive, and shear properties of beryllium in the temperature range from 800 to 1500 F for various strain rates are evaluated for beryllium of different grain sizes, fabrication characteristics, and oxide contents. Enhanced elevated temperature properties through grain boundary distribution of beryllium oxide in beryllium metal are shown, and the effects of grain size and crystal anisotropy at elevated temperature are discussed. The effects of purity, grain size, and other processing variables on the elevated temperature thermal properties, including thermal conductivity, specific heat, and coefficient of expansion, are also presented. Variations influencing chemical behavior are noted. Comparisons with some low-temperature properties are made to illustrate effects influenced by temperature and those independent of temperature.
