Abstract. This paper has been aimed to explore the influence of ageing process on sound velocity in C17200 copper–beryllium alloy. It was shown that the variation of sound velocity with ageing time follows a two-stage regime, the first stage with a sharp decreasing trend and the second stage developing with an almost constant velocity.

Beryllium work area means any work area where materials that contain at least 0.1 percent beryllium by weight are processed either: (1) During any of the operations listed in Appendix A of this standard; or (2) Where employees are, or can reasonably be expected to be, exposed to airborne beryllium at or above the action level.

The metal beryllium is mined by its extraction from the beryl ores. It does not occur free in nature. The mining of raw minerals such as bertrandite ore and beryl ore from the Earth's crust and volcanic rocks is required. Apart from beryl, beryllium is found in the mineral bertrandite, has become a major ore of the metal in the recent years.

Posted on May 10, 2019 by Brian Colwell. Beryllium, the lightest of the alkaline earth elements, has an atomic number of 4. As a consequence of its small ionic radius (about 0.27 angstroms), beryllium atoms bond strongly to other atoms forming compounds with great hardness and high melting temperatures. Uniquely strong and light, beryllium is ...

Etymologi. Ordet beryllium kommer af beryl og - (i)um i grundstofbetegnelser. Beryllium, der er et af de alkaliske jordartsmetaller, er et meget hårdt metal og anvendes som bestanddel af en række hårde legeringer. Rent metallisk beryllium anvendes i reaktorer og i rumfartsteknologi. Mange berylliummineraler anvendes som smykkesten.

Beryllium is used in nuclear reactors as a reflector or moderator because it has a low thermal neutron absorption cross section. Beryllium parts are tightly toleranced and heavily machined. Typically, 90 percent of beryllium stock is machined away during production. Though extreme, for example, a 44-pound part might result from machining …
