Contributors in Metallurgy

Metallurgy

Composite sheet produced by bonding either corrosion-resistant aluminum alloy or aluminum of high purity to base metal of structurally stronger aluminum alloy. The coatings are anodic to the core so ...

air cooling

Metals; Metallurgy

Cooling of the heated metal, intermediate in rapidity between slow furnace cooling and quenching, in which the metal is permitted to stand in the open air.

air-hardening steel

Metals; Metallurgy

A steel containing sufficient carbon and other alloying elements to harden fully during cooling in air or other gaseous mediums from a temperature above its transformation range. Such steels attain ...

aging

Metals; Metallurgy

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 ...

age hardening

Metals; Metallurgy

Hardening by aging, usually after rapid cooling or cold working. The term as applied to soft, or low carbon steels, relates to a wide variety of commercially important, slow, gradual changes that ...

activation

Metals; Metallurgy

The changing of the passive surface of a metal to a chemically active state. Contrast with passivation.

acid-process

Metals; Metallurgy

A process of making steel, either Bessemer, open-hearth or electric, in which the furnace is lined with a siliceous refractory and for which low phosphorus pig iron is required as this element is not ...
