Powder Metal Parts Terms
– Powder comprised of needle-shaped particles.
– A sintering
process whose rate is dramatically increased by something other than the
changing of temperature or time (e.g. adding a constituent to the powder,
thermal cycling or the atmosphere).
– A process
in which an air stream of controlled velocity is used to separate powder
into particle size fractions.
– The production
of metal powder by dispersing molten metal into individual particles through
mechanical methods or through the rapid movement of streams of liquids
or gases.
– A cementing medium
that is added to the powder to increase the green strength of the compact
and expelled during the sintering process. The term binder can also refer
to a material, typically having a lower melting point, that is added to
a powder mixture in order to bind powder particles together, which would
not have normally sintered into a strong body.
– An unfinished compact
that has already been pressed, presintered or fully sintered but requires
some other operation, such as cutting or machining, to bring it to its
completed form.
– The formation
of a metal compact through the compression of metal powder at room temperature.
– The process of
breaking down metal into individual particles through grinding and flaking
operations, among other procedures.
– A solid material consisting
of compressed metal powder that has been pressed in a die.
– A compact
consisting of more than one distinct substance.
– A press
tool consisting of a cavity and shaped according to part design requirements,
into which the metal powder is pressed to form a compact.
– Also referred to
as “sweating,” it is the rising of a compact component to
the top of the compact. During sintering, the component has a lower melting
point than that of the main compact constituent.
– A term that refers to
an object that has not been sintered.
– An increase in the
size of a compact that occurs during the sintering process.
– Process occurring
after the sintering process in which a nonmetallic substance, such as
oil, is used to fill the pores of the compact.
– Process occurring
either before or after the sintering process in which the pores of a compact
are filled with a metal substance having a lower melting point than that
of the compact.
– The production
of a compact through the application of uniform pressure from all directions
to metal powder.

– A fluid substance applied to the punch and die walls or mixed
into the metal powder to aid in the compaction process and compact removal.
– Another term for pressing
metal powder into a compact.
– The production
of more than one compact at a time by pressing metal powder in different
dies.
– Measurement reflecting
the percentage of open spaces, or pores, on a powdered metal part compared
to the volume of the part.
– Die component responsible
for pressing the metal powder into a compact. The punch makes contact
with the metal powder during the formation of a compact.
– A decrease in the
size of a compact that occurs during the sintering process.
– Deformations in a
compact resulting from the sintering process.
