Temperature Rise

แปลว่า(Concrete Engineering) The increase of concrete temperature caused by heat of hydration and heat from other sources.

Brine

แปลว่า(english) A saltwater solution for quenching or cooling when heat treating steel.

Bench-Blower

แปลว่า(english) A small core-blowing machine, utilizing a removable sand magazine and blow heat.

Bake

แปลว่า(english) Heat in an oven to a low controlled temperature to remove gases or to harden a binder.

Bazooka

แปลว่า(english) Performs functions of Galvanneal Furnace; set of torches on wheels used to shoot flames onto a strip to further heat it.

Burning 2

แปลว่า(english) Heating a metal beyond the temperature limits allowable for the desired heat treatment, or beyond the point where serious oxidation or other detrimental action begins.

Holding Period Period

แปลว่า(Concrete Engineering) In the manufacture of concrete products, the period between completion of casting and the introduction of additional heat or the steam curing period

Adiabatic Curing

แปลว่า(Concrete Engineering) The maintenance of ambient conditions during the setting and hardening of concrete so that heat is neither lost nor gained from the surroundings of the concrete.

Brasses

แปลว่า(english) Copper base alloys in which zinc is the principal alloying element. Brass is harder and mechanically stronger than either of its alloying elements copper or zinc. It is formable and ductile; develops high tensile strength with cold-working and is not heat treatable.

Aging 1

แปลว่า(english) A change in the properties of certain metal and alloys (such as steel) that occurs at ambient or moderately elevated temperatures after a hot working heat treatment or cold working operation. Typical properties impacted are hardness, yield strength, tensile strength, ductility, impact value, formability, magnetic properties, etc. See also Non-aging.

Brinell Hardness Testing

แปลว่า(english) Method of determining the hardness of materials; involves impressing a hardened ball of specified diameter into the material surface at a known pressure (10-mm ball, 500-kg load for aluminum alloys). The Brinell hardness number results from calculations involving the load and the spherical area of the ball impression. Direct-reading testing are generally used for routine inspection of forgings, and as a heat treat control function.

Aging 2

แปลว่า(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.
