Summary
Continuing efforts to investigate the effect of additives on the intermediate-temperatare (1000 to 2000 deg F) problems associated with the beryllides are described. Thermogravimetric oxidation-rate studies and modulus- ofrupture tests are being used to evaluate the properties of the beryllides containing additives. Metallographic examination of polished specimens before and after early stages of oxidation is being used to observe the effect of additives on the oxidation process, and thereby to gain insight as to the mechaniams through which these additives promote oxidation resiatance. Additives to ZrBe/sub 13/ such as Al, NiAl, Si, Ni, Sn, and Pt are being studied. The latter two elements did not significantly improve the oxidation resistance of ZrBe/sub 13/, but Si appears to offer considerable promise (in addition to AI and NiAl). Al also affords intermediate-temperatare oxidation resistance for Zr/sub 2/Be/sub 17/, and initial studies suggest the same results for NbBe/sub 12/. (auth)
