Vacuum Arc Remelting — (VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding applications. [ Modeling for Casting Solidification Processing , by Kuang Oscar Yu,CRC; 1st edition… … Wikipedia
Vacuum engineering — deals with technological processes and equipment that use vacuum to achieve better results than those run under atmospheric pressure. The most widespread applications of vacuum technology are: * Pyrolytic Chromium Carbide Coating * Antireflecting … Wikipedia
Electric arc furnace — An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 … Wikipedia
Electric arc — An electric arc is an electrical breakdown of a gas which produces an ongoing plasma discharge, resulting from a current flowing through normally nonconductive media such as air. A synonym is arc discharge. The phenomenon was first described by… … Wikipedia
Materials for use in vacuum — are materials showing very low rate of outgassing in vacuum, and, where applicable, tolerant to the bake out temperatures. The requirements grow increasingly stringent with the desired degree of vacuum achievable in the vacuum chamber. The… … Wikipedia
zone melting — a process of purifying any of various metals and other materials, as germanium or silicon, by passing it in bar form through an induction coil. Also called zone refining. Cf. cage zone melting. [1955 60] * * * Any of a group of techniques used to … Universalium
Shape memory alloy — A shape memory alloy (SMA, also known as a smart alloy, memory metal, or muscle wire) is an alloy that remembers its shape, and can be returned to that shape after being deformed, by applying heat to the alloy. When the shape memory effect is… … Wikipedia
Shape-memory alloy — A shape memory alloy (SMA, smart metal, memory metal, memory alloy, muscle wire, smart alloy) is an alloy that remembers its original, cold forged shape: returning the pre deformed shape by heating. This material is a lightweight, solid state… … Wikipedia
steel — steellike, adj. /steel/, n. 1. any of various modified forms of iron, artificially produced, having a carbon content less than that of pig iron and more than that of wrought iron, and having qualities of hardness, elasticity, and strength varying … Universalium
