摘要
相比于多数稀有金属,金属铍具有诸多优异性能,如比强度高、熔点高、杨氏模量高、比刚度大及热性能好等,故在导弹和航天器等高科技领域广泛应用。本文简要介绍了稀有金属铍的物理性能、影响微屈服强度(MYS)的因素和在核工业、航天航空等领域中的应用。
Compared with most rare metals,metal beryllium has many excellent properties,such as high specific strength,high melting point,high Young's modulus,high specific stiffness and good thermal performance,thus,it is widely used in high-tech fields such as missiles and spacecraft.This paper briefly introduces the physical properties of the rare metal beryllium,and the factors affecting the micro-yield strength(MYS)and its applications in the nuclear industry,aerospace and other fields.
