Materials Research for Advanced Inertial Instrumentation. Task 1. Dimensional Stability of Gyroscope Structural Materials.

Abstract

Macroyield experiments were performed on HIP-50 beryllium samples. These samples have been investigated for their microyield behavior during the last reporting period. Micro- as well as macroyield experiments were also performed on as-received and heat treated samples of the X-520 grade of beryllium and these results were compared with those obtained on HIP-50. Significant differences were observed for these two beryllium grades with respect to their 'micro' properties, even though their 'macro' properties were quite comparable. The microyield strength (MYS) values for as-received and heat treated HIP-50 samples were in the range of 17 to 27 kpsi; those for similarly heat treated X-520 samples, however, ranged only from about 8 to 9 kpsi.
