Decarburization is an important process during the heat treatment of steels. It can be divided into three separated events: dissolution of carbides, diffusion of carbon through the iron matrix, and surface reactions. The process is very sensitive to temperature. During intercritical annealing, austenite nucleates in the cementite-ferrite interface and grows at the rate determined by the diffusion of carbon in austenite. The presence of a decarburizing atmosphere during annealing guides the… 
The Kinetics of Formation and Decomposition of Austenite in Relation to Carbide Morphology
The effect of the carbide morphology on the kinetics of austenite formation and its decomposition was investigated by a combination of measurements of austenite fraction by dilatometry and
Temperature Dependence and Formation Mechanism of Surface Decarburization Behavior in 35CrMo Steel
Herein, the temperature dependence and formation mechanism of surface decarburization behavior are researched for 35CrMo steel in the temperature range of 710–950 °C. In view of the three
Thermal analysis and microstructure of oxide dispersion strengthened ferritic steels produced by ball milling with different amounts of process control agent
Fe–14Cr–3 W–0.4Ti–0.25Y2O3 ferritic steels were produced by ball milling of initial mixture of elemental powders with various amounts of process control agent (PCA), ethanol (0.25 mass%, 2.5 mass%, 4
Decarburization during laser surface processing of steel
Unwanted removal of carbon from surface may occur during laser surface processing of steels despite the short interaction time and thermal cycle. However, no attention is paid in literature to
Quantitative determination of carbon concentration profiles by GD‐OES for the study of decarburization in low‐carbon steels

Substantial changes in lattice parameters of ferrite and γ affected by not only thermal contraction but also transformation strains, thermal misfit strains and carbon enrichment in γ in the above hypoeutectoid steel are elucidated.
Influence of operating parameters on morphology of laser hardened surfaces
Conventional heat treatment of a component is performed in a furnace whereby the component is continuously heated to a high temperature and quenched to get a hardened material. The furnace heating
Carbon Contamination During Ion Irradiation - Accurate Detection and Characterization of its Effect on Microstructure of Ferritic/Martensitic Steels
The ability to quantify carbon contamination using three common techniques, namely time-of-flight secondary ion mass spectroscopy, atom probe tomography (APT), and transmission electron microscopy (TEM), is compared and their effectiveness and shortcomings in determining carbon contamination are presented and discussed.


Formation of Austenite During Intercritical Annealing of Dual-Phase Steels
