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.
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.
This would have been the result of faster cooling through the eutectoid
The relevant thermal parameters were liquidus temperature, lowest eutectic temperature, the recalescence, solidus, graphite factor 1, graphite factor 2, cooling rate at solidus, and eutectoid
With this information, the cooling rate for the different thermal moduli was experimentally calculated for the temperature range of the eutectoid
It has created by processing from liquid form by infiltration of vertical and descending capillary with binary eutectoid
alloy-Ag72Cu, of reinforcing from bidimensional and bidirectional twisting cupper wire under roll forming multiple capillary spaces in 3D, located within cylindrical cavity of cupper tube.
2, the isothermal transformation diagram for an iron-carbon alloy of eutectoid
composition that has been extended to lower temperatures.
The research team felt it necessary to understand and mathematically describe the metallurgical process during the solidification and eutectoid
transformation to simulate the development of the microstructure.
Structure of failure zones of the specimens, subjected to tensile tests at 20 and especially 700 [degrees]C, becomes more uniform; in addition to coarse inclusions fine particles of silicide phase are present, occurrence of which is possibly caused by eutectoid
disintegration under action of stress.
