Coupled temperature stress, phase transformation calculation model numerical illustration of the internal stresses evolution during cooling of a eutectoid
carbon steel cylinder.
Standard rail steel has a predominantly pearlitic structure with a nearly eutectoid
content of carbon and fine plates of pearlitic cementite.

The result of this show continued growth of austenite, passing the eutectoid
temperature during cooling requires a radical change.

Next to this phase, there is a very fine-grained eutectoid
formation, and within the grain there is a eutectoidic phase with a coarser cellular structure.
While limited results on X70 pipeline steels, a plain carbon steel of approximately eutectoid
composition (AISI 1080), and a relatively pure iron are included in these results, most of the results are for an X42 pipeline steel.
Aluminium and silica form the eutectoid
point (577 [degrees]C) at the silica content of 12.2% .
Characterization and morphological analysis of pearlite in a eutectoid
Among the 93 specific topics are texture development in aluminum friction stir welds, combining two x-ray diffraction settings for determining the texture of small sheared samples, the relative preference for strain localizations in ultra-low-carbon steel, eutectoid
point shift and orientation relationships between ferrite and cementite in pearlite in a high magnetic field, texture and microscopic evolution during the asymmetric rolling of magnesium alloys, and modeling rolling texture of twinned copper single crystals.
The most promising alloying elements in development of high-temperature, thermally stable titanium alloys are aluminium, gallium (they increase temperature of polymorphous transformation), zirconium and tin (which almost do not affect temperature of phase transformation), molybdenum, vanadium, niobium, tantalum (which do not have eutectoid
points with titanium), and silicon (it forms eutectics, that's why its content, as a rule, does not exceed 0.4%).
