摘要
本文评述了惯性器件用高性能铍材的发展，讨论了微屈服强度与应变指数和屈服强度之间存在的关系，最后得出结论：应同时使用ＭＹＳ和ｎ值反映材料的尺寸稳定性，以及可以用屈服强度取代微屈服强度。
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
