| Abstract: | In this paper the development on high performance beryllium materials used in inertial guidance instrument is described, the relationship between microyield strength (MYS), strain index (n) and yield strength (YS) is discussed. The conclusion is that dimension stability of material should be indicated by both MYS and n value and YS can be used instead of MYS |
