Unlike cementite, which has bonding reminiscent of ceramic materials, the hardness of martensite is difficult to explain in chemical terms. en.wikipedia.org

The martensite usually appears brighter yet flatter than the pearlite, and this is less dependent on the viewing angle. en.wikipedia.org

There is no thermal activation energy for the transformation from austenite to martensite. en.wikipedia.org

For example, appropriate quenching of steel can convert a desirable proportion of its content of austenite to martensite, creating a very tough product. en.wikipedia.org

However, greater undercooling by rapid quenching results in formation of martensite or bainite instead of pearlite. en.wikipedia.org

When austenite is cooled very suddenly by quenching in water the structure changes into martensite, which is an extremely hard form of steel. en.wikipedia.org

Further excessive heat-treatment brings about the decomposition of the martensite and reversion to austenite. en.wikipedia.org

When the edge cools fast a diffusionless transformation occurs, turning the austenite into very hard martensite. en.wikipedia.org

When austenite is allowed to cool slowly its structure changes into a mixture of ferrite and pearlite which is softer than martensite. en.wikipedia.org

To avoid the formation of pearlite or martensite, the steel is quenched in a bath of molten metals or salts. en.wikipedia.org
