(english) In hypoeutectoid steel, the temperature at which transformation of ferrite into austenite is completed upon heating.
(english) The intensity of deformation at a point in an object. See normal strain and shear strain.
(english) In two dimensions, a fixed support restrains three degrees of freedom: two translations and one rotation.
(Environmental Engineering) Water which is contained in geologic strata. Also properly written as two words, ground water.
(english) The ratio of shear stress divided by the corresponding shear strain in a linear elastic material.
(english) Forcing metal to flow in a direction opposite to the motion of a punch or die.
(Concrete Engineering) The water in concrete which is irremovable by oven drying; chemically combined during cement hydration.
(english) Joining metals by fusion of nonferrous alloys that have melting points above 800 F (425C), but lower than those of the metals being joined. May be accomplished by a torch. Filler metal is ordinarily in rod form in torch brazing; whereas in furnace and dip brazing the work material is first assembled and the filler metal may then be applied as wire, washers, clips, bands, or may be bonded, as in brazing sheet.
(english) 1) A furnace in which solid fuel (limestone, coke, iron ore) is combined with high-pressure, hot air blast (120,000 psi) to smelt ore in a continuous process (They are never stopped. They can be slowed down or idled). A Blast Furnace in the iron and steel industry is used to produce liquid iron.
(Concrete Engineering) A device used in determining time of setting of hydraulic cement, described in ASTM 0 266. Gradation The sizing of granular materials; for concrete materials, usually expressed in terms of cumulative percentages larger or smaller than each of a series of sieve openings or the percentages between certain ranges of sieve openings.
(english) Ingot mold, with the top constricted; used in the manufacture of capped steel, the metal in the constriction being covered with a cap fitting into the bottle-neck, which stops rimming action by trapping escaping gases.
(english) (1) The metal present in the largest proportion in an alloy; (2) the metal to be brazed, cut or welded; (3) after welding the part of the metal that was not melted during the process.
