Metallurgy
progressive aging
Metals; Metallurgy
An aging process in which the temperature of the alloy is continuously increased during the aging cycle. The temperature may be increased in steps or by any other progressive method. Compare with ...
proeutectoid
Metals; Metallurgy
Particles of a phase that precipitate during cooling after austenitizing but before the eutectoid transformation takes place.
primary crystal
Metals; Metallurgy
The first type of crystal that separates from a melt during solidification.
primes
Metals; Metallurgy
Metal products, such as sheet and plate, of the highest quality and free from visible surface defects.
process annealing
Metals; Metallurgy
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 ...
preheating
Metals; Metallurgy
Heating before some further thermal or mechanical treatment. For tool steel, heating to an intermediate temperature immediately before austenitizing. For some nonferrous alloys, heating to a high ...
