Cementite [PDF]

open access: yesInternational Materials Reviews, 2019
Cementite occurs in steels, in meteorites, possibly at the core of the Earth and has uses in its pure form. It's composition can deviate from , but not by much because the Fe–C bond contributes to its cohesion. Its crystallographic unit cell is orthorhombic and primitive, with large lattice parameters, explaining its hardness.

Thermal, compositional, and compressional demagnetization of cementite

open access: yesAmerican Mineralogist, 2015
The 1 bar Curie temperature, T C , at which cementite (anthropogenic form of the mineral cohenite, nominally Fe 3 C) abruptly loses ferromagnetism, is found to be sensitive to small deviations from the stoichiometric cementite composition. Stoichiometric Fe 3 C begins to lose magnetic susceptibility at 187 °C.

INFLUENCE OF ORIENTATION RELATIONSHIP BETWEEN FERRITE AND CEMENTITE IN PEARLITE ON STABIBLITY OF CEMENTITE PLATES

open access: yesMetallurgy and Foundry Engineering, 2007
The aim of the studies performed was to assess an influence of crystallographic orientation relationship (OR) between pearlitic ferrite and cementite on a stability of cementite plates. Diffraction analysis made with an electron microscope showed the existence of the Bagaryatski OR and the Pitsch OR both in the pearlite structure after eutectoid ...

Kinetic Modeling of Grain Boundary Cementite Evolution [PDF]

open access: yes, 2022
Prediction of grain boundary cementite growth kinetics in hypereutectoid steels is necessary to control its thickness. It is a question of major industrial importance but has remained unresolved to date. This paper presents and compares two different and

Mechanism of Si on the Cementite Type Transformation in As-cast High Carbon Chromium Bearing Steel [PDF]

open access: yesTeshugang
Four as-cast high carbon chromium bearing steels with different Si contents (0. 29%、0. 42%、0. 71% and 1. 50%)were prepared using a vacuum induction furnace, the carbides in the steel were extracted by nonaqueous solution electrolysis method.

Influence of Cementite Precipitation on Work Hardening Behavior in Ultrafine Grain Steels Rolled at Room and Cryogenic Temperatures

open access: yesMetals, 2022
The work hardening behavior of α + θ UFG steel related to α + θ two phase microstructure is more complicated than that of single-phase materials. Very few studies have been conducted on the work hardening of α + θ UFG steels.

INFLUENCE STRUCTURE ON THE PLASTICITY OF CARBON STEEL OF THE RAILWAY WHEEL RIM IN OPERATION [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2022
When simulating the operating conditions of the rim of a railway wheel, an analysis of change in the structural state from the possible degree of plastic deformation and the heating temperature of steel near the rolling surface was carried out.

Finite element analyses of elasto-plastic deformation in pearlite lamellar and colony structures [PDF]

open access: yes, 2015
Elasto-plastic tensile deformations in pearlite lamellar and two-colony structures are studied by finite element analyses to investigate the effects of lamellar thickness ratio and difference of lamellae orientation of two colonies in pearlite ...
