Nickel alloys that containing about 20% to 60% of iron and are used for their high magnetic permeability and electrical resistivity.
Copper base alloys to which phosphor has been added in the molten state for deoxidizing and strengthening purposes; known for its excellent toughness, strength, fine grain, resistance to fatigue and wear and chemical resistance.
A nonmetallic element that, in steels, increases strength and resistance to corrosion, and improves machinability.
Those properties familiarly discussed in physics, such as density or electrical conductivity.
The process of chemically removing oxides and scale from the surface of a metal by the action of water solutions of inorganic acids.
Permanent distortion of a material under the action of applied stresses.
The ability of a metal to be deformed extensively without rupture.
A thin coating of metal laid on another metal.
The finish obtained by buffing with rouge or similar fine abrasive, resulting in a high gloss or polish.
The art of producing metal powders and of utilizing metal powders for the production of massive materials and shaped objects.
A process of hardening an alloy in which a constituent precipitates from a supersaturated solid solution.
Precipitation Heat Treatment:
Any of the various aging treatments conducted at elevated temperature to improve certain of the mechanical properties through precipitation from solid solution.
A term used to describe heating applied as a preliminary to some further thermal or mechanical treatment.
In the sheet and wire industries, a process by which a ferrous alloy is heated to a temperature close to, but below, the lower limit of the transformation range and is subsequently cooled. This process is applied to soften the alloy for further cold working.
An aging process in which the temperature of the alloy is continually increased during the aging cycle. The temperature may be increased in steps or by any other progressive method.
