EFFECT OF ALLOYING ELEMNTS ON FERRITE GROWTH IN FE‐C‐X TERNARY ALLOYS

Panahi, Damon 10 1900 (has links)
<p>A self‐consistent model for non‐partitioning planar ferrite growth from alloyed austenite is developed. The model captures the evolution with time of interfacial contact conditions for substitutional and interstitial solutes. Substitutional element solute drag is evaluated in terms of the dissipation of free energy within the interface, and an estimate is provided for the rate of buildup of the alloying element ‘‘spike’’ in austenite. The transport of the alloying elements within the interface region is modeled using a discrete‐jump model, while the bulk diffusion of C is treated using a standard continuum treatment.</p> <p>The model is validated against ferrite precipitation and decarburization kinetics in the Fe‐Ni‐C, Fe‐Mn‐C, Fe‐Mo‐C, Fe‐Si‐C, Fe‐Cr‐C and Fe‐Cu‐C systems.</p> / Doctor of Philosophy (PhD)
