“…In Fe-C-Mn ternary alloys, it is consistently reported that the measured growth rate is significantly higher than the predicted growth rate with PLE condition in the partitioned growth region but smaller than that under PE condition in the unpartitioned growth region. [28,29] In Fe-C-Si and Fe-C-Al alloys, however, it is reported that the measured growth rate constant agrees well not only with the paraequilibrium calculation but also with the local equilibrium calculation because the growth rate constants calculated under the PE and NPLE are similar. [15] The temperature dependence of growth kinetics in the investigated Fe-C-Mn-Si and Fe-C-Mn-Si-Al alloys is comparable with that in Fe-C-Mn ternary alloy.…”

The growth kinetics of proeutectoid ferrite in the early stages of transformation were studied in Fe-0.1C-1.5Mn-1Si (mass pct) quaternary and Fe-0.1C-1.5Mn-1Si-0.2Al quinary alloys. The observed kinetic transition temperatures from partitioned slow growth to unpartitioned fast growth of ferrite in both alloys are in good agreement with predictions using a local equilibrium model for multicomponent systems. The measured parabolic growth rate constants were smaller than those calculated assuming paraequilibrium in the unpartitioned growth region, but the difference between the measured and the calculated growth rate constants gradually diminished with a decreasing reaction temperature. The dissipation of driving force, derived from the diffusion of the substitutional solute within the transformation interface, possibly constitutes a major part of the discrepancy between the measured and the calculated growth kinetics.

“…So far, the research on magnetic field related topics focuses on the following aspects: martensite [1e3], bainite [4], ferrite [5] and pearlite [6] transformations, the nucleation and growth of cementite [7], and carbide precipitation [8]. Recently more attention has been paid to the precipitation sequence and growth behavior of iron carbides which is influenced by high magnetic fields [9,10].…”

“…[85] In a Fe-0.1 pct C-3 pct Mn alloy, the parabolic growth rate constants increased a few times in both partitioned and nonpartitioned growth by a magnetic field of 8 T, which was somewhat greater than the amount of increase in the growth under local equilibrium. [86] In a recent experimental study aimed at determining whether a Fe-C-Mo alloy exhibits the TTT-bay and transformation stasis in a strong magnetic field, [87] it was shown that the stasis did occur and that the bay temperature was raised more than 30 K in a magnetic field of 12 T. This could be accounted for largely by the thermodynamic effects, namely, by the relative stabilities of ferrite and austenite in the magnetic field. Moreover, in a magnetic field of 8 T, the acceleration of pearlite transformation was observed in hypoeutectoid Fe-0.4 pct C-2 pct Ni alloy, the amount of acceleration relative to ferrite being greater at low undercoolings.…”

ALEMI is concerned with the interactions between Alloying Elements and Migrating Interfaces. A first meeting was held in conjunction with the 2000 TMS Fall Meeting in St. Louis, MO. About 22 attendees endorsed the principles contained in the invitation, which envisaged a more collaborative approach to the study of alloying element interactions with transformation interfaces, especially in alloy steels. The meetings were intended to be informal workshops emphasizing the sharing of ideas and plans for research. The development of a shared stock of alloys for research was planned, as well as the publication of summaries of discussions in an open, preferably archival, forum. Eight further meetings were held, often in conjunction with major conferences. An approximate equilibrium developed between discussions of theoretical matters and experimental results and methods. A remarkable number of those who attended the first meeting in St. Louis continued to participate. Research ideas were put forward, issues debated, collaborations fostered, and the science of transformation interfaces advanced.
