[en] The light metal beryllium is a comparatively rare element, which today is primarily derived from bertrandite. It is mainly used as pure metal or in the form of copper-beryllium alloys, e.g., in automotive industry, aerospace, and electrical components. The wide range of applications is mainly attributed to the extremely high rigidity/density ratio. An overview of the history of the metal, its production, and recycling as well as the properties of CuBe alloys are given.
[en] The possibility of monitoring structure homogeneity has been studied by the method of Mössbauer spectroscopy with a resonance detector on the example of beryllium alloys, containing from 0.09 to 0.8 wt.% iron and other metallic impurities with a total amount of 0.04 to 0.14 wt.%. The quality of the obtained spectra description has been improved using methods which have a different degree of complexity and effectiveness.
