Abstract

|
|
|
| The effect of Cr on the kinetics of ferrite growth from austenite was studied using the technique of controlled decarburization over the temperature range 850 °C to 775 °C. At 850 °C, the observed ferrite growth kinetics is in excellent agreement with the predictions of the local equilibrium negligible partition (LENP) model. At temperatures below 850 °C, the growth kinetics becomes increasingly slower than the predictions of the LENP model. This was interpreted in terms of the solute-drag effect of Cr, and the cross-boundary diffusion coefficient of Cr was estimated. |
