Light Microscopy of Carbon Steels
The overall difficulties attending the definition of martensite as a product of a
martensitic transformation are clearly very complex and can be stated in many
ways, but probably none better than the concluding comments by Parr (in Ref 4):
The ...

Steel Heat Treatment: Metallurgy and Technologies
At lower temperatures the intermediate (bainite) transformation takes place, and
at higher undercooling rates martensite (diffusionless) transformation occurs. 4.2.
2 Effect on Martensite Transformation As in carbon steels, the martensite ...

Surface Hardening of Steels: Understanding the Basics
Lightly tempered martensite is the dominant microstructural constituent of
properly carburized steel. However, the martensite changes in morphology,
amount, and properties as a function of distance from the surface. Other case
microstructural ...

Modern Physical Metallurgy and Materials Engineering: ...
Thus, when cooling is resumed martensite forms only after an appreciable drop
in temperature. Such thermal stabilization has been attributed by some workers
to an accumulation of carbon atoms on those dislocations important to martensite
...
R. E. Smallman, Ray J. Bishop, 1999

Principles of the Heat Treatment of Plain Carbon and Low ...
Fig 9-32 The hardness of martensite as a function of carbon content, taken from
several sources. Points from the dashed curve were fitted to obtain the equation
given, and the prominent points were calculated from this equation. (Adapted
from ...
Ideally, in plain carbon and low-alloy steels, the highest hardness is achieved by
forming microstructures that consist entirely of martensite. A completely
martensitic structure is unattainable, however, even if the transformation of
austenite to ...

Steel Metallurgy for the Non-metallurgist
Often, these steels are heat treated to produce a spheroidized cementite structure
in a matrix controlled by the final cooling, which may consist of fine pearlite,
bainite, or tempered martensite. Summary of the Major Ideas in Chapter 4 1.

Steel Castings Handbook
This structure is referred to as martensite and is found in fully hardened steels.
Microstructurally, martensite has the appearance of needles. Since martensite
occupies a greater volume than austenite, steel expands when martensite forms,
and ...

diameter of the equivalent circle around each martensite grain and its average
size by a statistical method. We defined the average size of martensite grain
estimated in this way as the equivalent grain size of martensite. Fig. 9 Qualitative
