81alkali metal — Chem. any of the group of univalent metals including potassium, sodium, lithium, rubidium, cesium, and francium, whose hydroxides are alkalis. [1880 85] * * * Any of the six chemical elements in the leftmost group of the periodic table (lithium,… …
82hand tool — any tool or implement designed for manual operation. * * * Introduction any of the implements used by craftsmen in manual operations, such as chopping, chiseling, sawing, filing, or forging. Complementary tools, often needed as auxiliaries to… …
83Sheffield plate — sheet copper with a cladding of silver. [1855 60; named after SHEFFIELD, England] * * * Articles made of copper coated with silver by fusion. The technique was discovered с 1742 by the Sheffield (Yorkshire, Eng.) cutler Thomas Boulsover, who… …
84deformation and flow — Alteration in size or shape of a body under the influence of mechanical forces. Flow is a change in deformation that continues as long as the force is applied. Gases and liquids normally flow relatively freely, while solids deform when subjected… …
85industrial glass — Introduction solid material that is normally lustrous and transparent in appearance and that shows great durability under exposure to the natural elements. These three properties lustre, transparency, and durability make glass a favoured… …
86nickel processing — Introduction preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a… …
87metal — One of the electropositive elements, either amphoteric or basic, usually characterized by properties such as luster, malleability, ductility, the ability to conduct electricity, and the tendency to lose rather than gain electrons in chemicals. [L …
88Carbon-fiber-reinforced polymer — For fibers of carbon, see carbon (fiber). Tail of an RC helicopter, made of CFRP Carbon fiber reinforced polymer or carbon fiber reinforced plastic (CFRP or CRP or often simply carbon fiber), is a very strong and light fiber reinforced polymer… …
89Casting (metalworking) — Casting iron in a sand mold In metalworking, casting involves pouring liquid metal into a mold, which contains a hollow cavity of the desired shape, and then allowing it to cool and solidify. The solidified part is also known as a casting, which… …
90Dynamic strain aging — Although sometimes dynamic strain aging is used interchangeably with the Portevin–Le Chatelier effect (or serrated yielding), dynamic strain aging refers specifically to the microscopic mechanism that induces the Portevin–Le Chatelier effect.… …
