惯性器件用铍材微屈服强度的研究

Microyield Strength of Beryllium Materials Used in Inertial Guidance Instrument

介绍了惯性器件用铍材微屈服强度（ＭＹＳ）的研究概况、测试方法，讨论了晶粒尺寸、杂质（主要是ＢｅＯ）、热处理与微合金化等对铍材ＭＹＳ的影响。结果表明，采用粒径细小低氧化铍的冲击研磨粉末和等静压固结工艺是获得高ＭＹＳ铍材的重要途径。

Survey is made of study and testing methods of microyield strength(MYS) of beryllium materials used in inertial guidance instrument. The influence of grain size, impurity (BeO), heat treatment and microalloying on MYS of beryllium is discussed. The conclusion is that impact attritioned powder with finer grain size and lower oxide content and its isostatic press ing consolidation are an important way to obtain high MYS beryllium materials.
