martensite's Usage Examples:

When viewed through a magnifying lens, the nioi appears as a sparkly line, being made up of many bright martensite grains, which are surrounded.

carbides within a tempered martensite or pearlite matrix in higher carbon steel, or by ferrite and pearlite banding in lower carbon steels.

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

martensite; however, very slow cooling rates caused by high preheat or a combination of preheat and high heat input from the weld procedures can create a.

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

structure known as martensite (daughter phase).

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

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

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

NiTi alloys change from austenite to martensite upon cooling;.

quenching steel causes the austenite to transform into martensite, all of the austenite usually does not transform.

re-transformation of the induced martensite back to austenite or to ferrite plus cementite, negating the hardening effect.

many steels are quenched to produce an overabundance of martensite, then tempered to gradually reduce its concentration until the preferred structure for.
