Summary on Grant Application Form |
|
In the past thirty years or so, there has been remarkable progress in the collection and assessment of thermodynamic data for metals and alloys. Such work is near fruition, since there are now available several software systems capable of estimating the phase diagram as a function of pressure, temperature. However, in many applications use is made of metastable microstructural configurations, so that the kinetics of transformations need to be addressed. The proposed work would involve modelling the movement of ferrite/austenite, austenite/cementite and ferrite/cementite boundaries in steels, under the local equilibrium hypothesis. Extension to the paraequilibrium mode (in which substitutional elements do not partition) will be attempted. Existing thermodynamic data and thermodynamic models will be employed. Comparisons with experimental data taken from the literature will be made. The breakdown of the local equilibrium mode to the paraequilibrium mode will be modelled, by identifying and including the processes which dissipate free energy. This represents the first step in attempting to explain the transition from diffusional to displacive growth.
