In Situ Investigation of the Iron Carbide Precipitation Quenching and Partitioning (Q&P) steels are promising candidates for automotive applications because of their lightweight potential. Their properties depend on carbon enrichment in austenite which, in turn, is strongly influenced by carbide precipitation in martensite during quenching and partitioning treatment. In this paper, by coupling in situ High Energy X-Ray Diffraction (HEXRD

Microstructure of Martensite in FeCCr and its

The microstructure of as-quenched martensite in four FeCCr alloys (0.15C-1Cr, 0.15C-4Cr, 1C-1Cr, 1C-4Cr, mass%) has been investigated. Moreover, the microstructures served as input for setting up modeling of carbide precipitation during tempering of martensite. Precipitation process of vanadium carbide in M 23 C 6 by Sep 03, 2019 · Abstract The effect of vanadium (V) on the nucleation of M 23 C 6 and vanadium carbide (VC) precipitation in FeCrV alloy was studied by field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy and thermodynamic calculations. Simulation of -Carbide Precipitation Kinetics in Aged Low The carbide precipitation started early and increased significantly to 14% after 30 min of aging. After approximately 1000 min of aging, the carbide phase fraction was relatively steady at ~ 14%. This amount was slightly lower than the calculated equilibrium phase fraction of 16.5%, which indicates that precipitation was nearly complete.

Carbide precipitation during stage I tempering of Fe-Ni-C

Dec 01, 1989 · The carbide particles contain a fine internal substructure which appears to represent an internal accommodation deformation (faulting) on the carbide basal plane. Detailed analysis of the kinematics of carbide precipitation suggests that the observed habit plane and accommodation deformation permit an invariant-plane strain transformation which minimizes elastic strain energy.
