Correlation between Hardening Characteristic of Carbon SteeI and Dispersion of Cementite [PDF]

, 1999
Hardening charactertic of carbon steels have been discussed by comparing the flow curves with the shape and distribution of cementite. The complicated microstructure state induding lamellar or granular cementite has been quantitatively estimated with one

X-ray diffraction and Mossbauer spectroscopy studies of cementite dissolution in cold-drawn pearlitic steel

, 2013
Cementite dissolution in cold-drawn pearlitic steel (0.8 wt.% carbon) wires has been studied by quantitative X-ray diffraction (XRD) and Mossbauer spectroscopy up to drawing strain 1.4.

Carbon diffusion in cementite: a molecular dynamics study

In this paper, carbon diffusion in cementite is studied by molecular dynamics simulation. An assumption that carbon-carbon interaction occurs only indirectly via neighbouring iron atoms is used.

Phonons and elasticity of cementite through the Curie temperature [PDF]

, 2017
Phonon partial densities of states (pDOS) of ^(57)Fe_3 C were measured from cryogenic temperatures through the Curie transition at 460 K using nuclear resonant inelastic x-ray scattering.

Atomic mechanism of carbon diffusion in cementite

Molecular dynamics is employed to investigate carbon diffusion in cementite. An approximation that carbon atoms can interact with each other only indirectly (via neighbouring iron atoms) is used.

Cementite in the Fe-N-C system

, 2008
Gasnitrieren und Gasnitrocarburieren sind thermochemische Wärmebehandlungsverfahren, die gewöhnlich unterhalb der binären/ternären eutektoiden Temperatur des Fe-N/Fe-N-C Mischkristalls durchgeführt werden. Diese Prozesse resultieren in der Ausbildung einer (i) Diffusionszone, wo Stickstoff und/oder Kohlenstoff in den Oktaederlücken des krz-Eisens ...

Evaluation of Grindability of Steels by Grain Size of Cementite

The spheroidization of cementite has been used as one method for improving steel characteristics.\nIn this study the spheroidized cementite grain was examined, and an experiment was performed with regard to the effect of the grain size on the grinding ...

Measurement of stiffness of cementite using in-situ electron microscopy

, 2012
학위논문 (석사)-- 서울대학교 대학원 : 재료공학부, 2012. 2. 김영운.세멘타이트(cementite)는 철강의 강도를 지배하는 중요한 상(phase)으로 고려되어 왔다. 하지만 세멘타이트가 주로 페라이트(ferrite)와의 복합상으로 적용되며 단일상 시편제작이 어렵기 때문에 시멘타이트 단일상의 물성은 잘 알려져 있지 않다.

Relations between graphite and cementite in pure iron-carbon alloys.

, 1937
The history of the iron-carbon equilibrium diagram has been reviewed, with special reference to relations between the graphite-iron andcementite-iron systems.Several factors influencing the relative tendencies for graphite and cementite to occur have ...
