martensite's Usage Examples:

transforms into martensite, a body centered tetragonal structure (BCT).

The rate of cooling determines the relative proportions of martensite, ferrite, and.

the size and distribution of carbides in the martensite, forming a microstructure called "tempered martensite".

just above the martensite start temperature (Ms).

By using interrupted quenching, the cooling is stopped at a point above the martensite transformation.

structure known as martensite (daughter phase).

There are four transition temperatures associated to the austenite-to-martensite and martensite-to-austenite.

change an alloy's properties during heat treatment: the formation of martensite causes the crystals to deform intrinsically, and the diffusion mechanism.

twinned martensite, detwinned martensite and austenite) and six possible transformations.

NiTi alloys change from austenite to martensite upon cooling;.

described the microstructure as being similar in appearance to tempered martensite.

austenitic and unable to transform to martensite when heat treated, while lower-nickel steels can transform to martensite.

of martensite or bainite instead of pearlite.

This is possible provided the cooling rate is such that the cooling curve intersects the martensite start.

cooling it at different rates, turning part of the object into very hard martensite while the rest cools slower and becomes softer pearlite.

It is designed to increase the amount of martensite in the steel's crystal structure, increasing its strength and hardness.

migrate but is locked within the face-centered austenite and forms martensite.

metallurgy, quenching is most commonly used to harden steel by inducing a martensite transformation, where the steel must be rapidly cooled through its eutectoid.

or at a high rate, trapping the carbon within the iron thus forming martensite.

austenite as austenite transforms to ferrite on slow cooling, or from martensite during tempering.

bainite can develop instead of pearlite, and with very rapid cooling martensite can develop.

liquid to form an amorphous solid, and cooling eutectoid austenite to form martensite.

The quenching results in the formation of metastable martensite, the fraction of which is reduced to the desired amount during tempering.

martensite's Meaning':

a solid solution of carbon in alpha-iron that is formed when steel is cooled so rapidly that the change from austenite to pearlite is suppressed; responsible for the hardness of quenched steel
