Progress on the properties of intermetallic beryllides and silicides under investigation is reported. Evaluation of the oxidation resistance of Hf/ sub 2/Be/sub 21/ and WSi/sub 2/ is discussed. Introductory work on the quantitative determination of the rate of oxidation of ZrBe/sub 13/ is reported. The oxidation products of this compound are identified as ZrBe/sub 17/ and BeO and the over-all rate of oxidation follows the cubic rate law. Thermal expansion data for WSi/sub 2/ and enthalpy data for Ta/sub 2/Be/sub 17/ are given. With these data the experimental measurement of thermal expansion and enthalpy are completed for all the compounds under investigation. Additional transverse- rupture data are reported for WSi/sub 2/ and Hf/sub 2/Be/sub 17/. (auth)
