Ac3

แปลว่า(english) In hypoeutectoid steel, the temperature at which transformation of ferrite into austenite is completed upon heating.

Strain:

แปลว่า(english) The intensity of deformation at a point in an object. See normal strain and shear strain.

Fixed support:

แปลว่า(english) In two dimensions, a fixed support restrains three degrees of freedom: two translations and one rotation.

Groundwater

แปลว่า(Environmental Engineering) Water which is contained in geologic strata. Also properly written as two words, ground water.

Shear modulus:

แปลว่า(english) The ratio of shear stress divided by the corresponding shear strain in a linear elastic material.

Backward Extrusion

แปลว่า(english) Forcing metal to flow in a direction opposite to the motion of a punch or die.

Non-evaporable Water

แปลว่า(Concrete Engineering) The water in concrete which is irremovable by oven drying; chemically combined during cement hydration.

Brazing

แปลว่า(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.

Blast Furnace

แปลว่า(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.

Gillmore Needle

แปลว่า(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.

Bottle Top Mold

แปลว่า(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.
