Examples of martensite
martensite
The martensite causes shallow, widening cracks on the wheels, or spalling.

There is no thermal activation energy for the transformation from austenite to martensite.
From the en.wikipedia.org
After quench hardening, the microstructure of the material form into martensite as a fine, needle-like grain structure.
From the en.wikipedia.org
Martensite has a lower density than austenite does, so that transformation between them results in a change of volume.
From the en.wikipedia.org
By applying strain to the metal, the austentite undergoes a phase transition to martensite without the addition of heat.
From the en.wikipedia.org
Using an electron microscope, they discovered that Cola's process did indeed form martensite microstructure inside the steel.

The three sets of twinned lamellae are thus three variants of a martensite, forming three domains that later impinge and intersect.

Perhaps the most important polymorphic form is martensite, a metastable phase which is significantly stronger than other steel phases.
From the en.wikipedia.org
As soon as the train stops, the wheels cool quickly, causing a thin layer of steel to transform into a brittle, untempered form called martensite.

- 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
- Martensite, named after the German metallurgist Adolf Martens (1850u20131914), most commonly refers to a very hard form of steel crystalline structure, but it can also refer to any crystal structure that is formed by diffusionless transformation. It includes a class of hard minerals occurring as lath- or plate-shaped crystal grains...
- Martensitic refers mainly to stainless types 410, 416 and 420. Named for Robert Martens, these grades have a high carbon content which reduces corrosion resistance but allows a sharp increase in tensile strength after heat treatment. ...
- Martensitic stainless steels are alloys of chromium and carbon. They are ferromagnetic, hardenable by heat treatments, and are usually less resistant to corrosion than some other grades of stainless steel. Chromium content usually does not exceed 18%, while carbon content may exceed 1.0 %.
- (Martensitic) A small category of magnetic stainless steels typically containing 12% chromium, a moderate level of carbon, and a very low level of nickel.
- (Martensitic) Refers to atomic arrangement and in the case of steels, is a modified body centred cubic structure. These steels can be heat treated because martensite is iron carbide, which is very hard. However, these steels can be hydrogen embrittled and will rust. ...
- (Martensitic) a highly twinned lower temperature structure with a stress-strain curve having a plateau phase more like that of an elastomer than a metal; compare austenitic.
- A generic term for microstructures formed by diffusionless phase transformation in which the parent and product phases have a specific crystallographic relationship. Martensite is characterized by an acicular pattern in the microstructure in both ferrous and nonferrous alloys. ...
- A component of iron useful for determining heat treating techniques used, it is a solution of iron and up to 1% carbon.
