  We do Monte Carlo simulations of four 3D structural transitions, with
vector-spin models of their martensitic strain domains under quenches to $T$,
to test a generic post-quench Partial Equilibration Scenario (PES) of Ritort.
We indeed confirm that energy-lowering passages between fixed-energy shells
induce a signature PES distribution of an exponential tail in heat releases,
scaled in an effective search temperature. A linear vanishing of this
$T_{eff}(T)\sim T_d -T$ at a temperature $T_d$ where PES passage-searches
freeze, explains the Vogel-Fulcher like divergence of equilibration times $
e^{1/ T_{eff} (T)}\sim e^{1/(T_d -T)}$, extracted from incubation-time delays
of simulations and martensitic alloys.
