AbstractDThe kinetic transition between partitioned and unpartitioned growth of
proeutectoid ferrite has
been studied for high-purity Fe±C±Mn and Fe±C±Ni alloys, and for temperatures just
above the eutectoid.
These results (and certain results of previous investigations) are compared with
computed paraequilibrium
and equilibrium ternary phase diagrams, and it is shown that the transition occurs well
within the para-
equilibrium two-phase regions, but signi®cantly outside the
