| A Coatings |
(English) Coatings on hot-dipped galvanized steels processed to convert the coating completely to zinc-iron alloys; dull gray in appearance, have no spangle, and after proper preparation, are well suited for painting.

| Addition Agent |
(english) 1) Any material added to a charge of molten metal in bath or ladle to bring alloy to specifications, 2) reagent added to plating bath. |
| Adeline Steelmaking Process |
(english) Method of producing a precision casting of steel or steel alloys using aluminolthermic process and lost wax, followed by centrifugal action. |
| Aging 1 |
(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. |
| Aging 2 |
(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. |
| Babbitt |
(english) An antifriction metal alloy used for bearing inserts;made of tin,antimony,lead and copper. |
| Banding |
(english) Inhomogeneous distribution of alloying elements or phases aligned in filaments or plates parallel to the direction of working. |
| Base Metal |
(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. |
