austemper

As a noun ausferrite

is a special type of microstructure that occurs when ductile iron is austempered, consisting of acicular ferrite in carbon-enriched austenite.

As a verb austemper is

to harden (a metal) and produce a stronger microstructure by heating it into the austenite region and then immediately quenching and removing any bainite and ausferrite.

As a noun bainite

is a microstructure of steel consisting of needle-like particles of cementite embedded in a ferrite matrix.

As a verb austemper is

to harden (a metal) and produce a stronger microstructure by heating it into the austenite region and then immediately quenching and removing any bainite and ausferrite.

In lang=en terms the difference between quench and austemper

is that quench is to cool rapidly by dipping into a bath of coolant, as a blacksmith quenching hot iron while austemper is to harden (a metal) and produce a stronger microstructure by heating it into the austenite region and then immediately quenching and removing any bainite and ausferrite.

As verbs the difference between quench and austemper

is that quench is to satisfy, especially an actual or figurative thirst while austemper is to harden (a metal) and produce a stronger microstructure by heating it into the austenite region and then immediately quenching and removing any bainite and ausferrite.

As a noun quench

is (physics) the abnormal termination of operation of a superconducting magnet, occurring when part of the superconducting coil enters the normal (resistive) state.

As a noun austenite

is austenite.

As a verb austemper is

to harden (a metal) and produce a stronger microstructure by heating it into the austenite region and then immediately quenching and removing any bainite and ausferrite.

As a noun microstructure

is the fine structure of a material or tissue as revealed by microscopy.

As a verb austemper is

to harden (a metal) and produce a stronger microstructure by heating it into the austenite region and then immediately quenching and removing any bainite and ausferrite.

As verbs the difference between harden and austemper

is that harden is to become hard (tough, resistant to pressure) while austemper is to harden (a metal) and produce a stronger microstructure by heating it into the austenite region and then immediately quenching and removing any bainite and ausferrite.
