(Environmental Engineering) (FS) are the solids that do not volatilize at 550°C.
(english) Firing a mold at a high temperature to remove pattern material residue.
(Concrete Engineering) The addition of water to the cement mix whether at the batch plant, during transit or at the jobsite to achieve the specified water to cement ratio.
(Environmental Engineering) The depth at which an inflection point occurs in a lake temperature profile.
(Environmental Engineering) An organic compound with a carbonyl at one end of a hydrocarbon group.
(english) A three-roll cluster used to control line tension at strategic locations on the line.
(english) In hypereutectoid steel, the temperature at which cementite goes into complete solution with austenite.
(english) Machine located at each delivery reel to automatically place circumference bands around completed coils.
(english) The proportional constant between stress and strain for material with linear elastic behavior: calculated as stress divided by strain. Modulus of elasticity can be interpreted as the slope of the stress-strain graph. It is usually denoted as E, sometimes known as Young's Modulus Y, or E-Modulus.
(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures.
(english) Work done primarily at a bench with hand tools. Occasionlly suplemented by small power-driven tools.
(Software Engineering) a point at which manager or the customer decides whether the project should proceed
