On carbon distribution in austenite Fe‑C alloys

چکیده
Based on the calculations of model elementary crystal cell γ‑iron, it is shown that carbon ions cannot be present in its open pores. Carbon Fe‑C alloys dissolves and distributes mainly as graphite nanocrystals. In steel austenite, found nanocrystals iron‑carbon complexes. cast iron

Diffusion of carbon in substitutionally alloyed austenite
where k and h are the Boltzmann and Planck constants, respectively, W is the number of octahedral interstices around a single such interstice, ~F* is an activation free energy, r m is an activity coefficient and), is the distance betwe-en (002) austenite planes. <1'= 1exp(-wy/kT); Wy is the nearest neighbour carbon-carbon interaction energy in austenite. () is the ratio of the number of carbon ...
متن کاملSolubility of carbon in tetragonal ferrite in equilibrium with austenite
There are precise observations which indicate the reluctance of excess carbon within bainite or martensite to partition into adjacent austenite in spite of prolonged heat treatment at temperatures where carbon is mobile. To explain this, we report the first calculations of the solubility of carbon in tetragonal ferrite that is in equilibrium with austenite. It is found that the solubility is dr...
متن کاملCarbon Diffusion in Austenite: Computer Simulation and Theoretical Analysis
1. Introduction Carbon interstitial diffusion in austenite (γ-Fe) has been studied experimentally and analytically for many years. Two experimental studies have been made of carbon diffusion in austenite at low carbon contents. One is a measurement of the carbon chemical or intrinsic diffusion coefficient at 1075 K, 1124 K and 1273 K, and as a function of carbon content [1]; the other is a meas...
متن کاملA Commentary on: ‘‘Diffusion of Carbon in Austenite with a Discontinuity in Composition’’
CONSIDER an allotropic transition between two phases in a pure substance. The phases are said to be in equilibrium when they have identical free energies. Pure ice and water coexist at precisely 273.15 K (0 C) and 1 atm of pressure. When this system consists of a mixture of common salt and H2O, the ice and water become solid and liquid solutions, respectively, but can still coexist in equilibri...
متن کاملExamination of carbon partitioning into austenite during tempering of bainite
The redistribution of carbon after tempering of a novel nanocrystalline bainitic steel consisting of a mixture of supersaturated ferrite and retained austenite has been analyzed by atom probe tomography. No direct evidence supporting the additional carbon enrichment of austenite beyond that initially achieved during the bainite heat treatment was obtained during subsequent tempering of this hig...
