martensite meaning in Hindi

The microstructures of martensite and bainite at first seem quite similar.
Thus, martensite can be thermally induced or stress induced.
Bainite is an intermediate of pearlite and martensite in terms of hardness.
In this figure, ? ( T ) represents the martensite fraction.
The transition from martensite to austenite produces force and deformation.
There is no thermal activation energy for the transformation from austenite to martensite.
However, the martensite transformation is time-independent.
A very rapid quench is essential to create martensite.
Untempered martensite is low in toughness and therefore brittle.
The strength of the martensite is reduced as the amount of retained austenite grows.

noun.

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
