molting, priming, infiltration, locking and solidification of eutectoid alloy Ag-Cu, having parameters: heating speed-[v.
where 1 is width of hipoeutectoid zone, urn; 2 is width of eutectoid zone, um; 3 is hypereutectoid range going gradually to the microstructure of core, um.
Factors that can influence tool life and machinability include metallurgical conditions, such as graphite size and distribution, composition, ferrite/ pearlite ratio, cooling rate from the eutectic through the eutectoid temperatures, and the presence of either endogenous or exogenous inclusions (Fig.
The mechanism by which Sn stabilizes pearlite is achieved by blocking diffusion of C from the matrix to graphite flakes during the eutectoid reaction.
The microstructure analysis had showed carbides undistinguished in the hypereutectoid zone because of high dispersion, also the boundary was not visible between hyper- and eutectoid zones.
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.
Failure analysis of cold drawn eutectoid steel wires for prestressed concrete, Engineering Failure Analysis 13(3): 301-311.
Standard rail steel has a predominantly pearlitic structure with a nearly eutectoid content of carbon and fine plates of pearlitic cementite.
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.
Characterization and morphological analysis of pearlite in a eutectoid steel.
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.
