The investigation of refractory metal beryllides and silicides for very high temperature (>2500 deg F) applications for short-time use, 10 hours or less, was continued. Some of the properties of Ta/sub 2/Be/sub 17/ and WSi/sub 2/ as a function of stoichiometry, particularly in the intermediate temperature region, are reported and discussed. Tests included modulus of rupture, thermal shock, and oxidation resistance measurements. The first of a series of vapor pressure measurements on selected beryllides using a direct weighing Knudsen cell technique is reported for ZrBe/sub 13/. Also, a preliminary analysis of Zr/sub 2/ Be/sub 17/ oxide scales for products is reported. (auth)
