defined incubation time that sensitively depends on the depth of the quench, $T_0 - T_f$. Moreover, for $T_f < T_{sp}$, with $T_{sp}$ deduced from static correlations, we observe domain patterns typical to spinodal ordering. In the long–time coarsening regime we extract anisotropic scaling functions. Our model is a limiting case where type-I domain walls have exactly zero formation–energy and therefore are extremely stable. Within our accessible time window we find coarsening exponents which are significantly smaller than the conventional exponent $\alpha=1/2$ for curvature–driven coarsening.[@Lifsh; @AllenC]

After shortly explaining our model and simulation techniques in section \[MODEL\], we compare in section \[THERMALACT\] ordering processes that occur for shallow ($T_0 >T_f>T_{sp}$) and deep ($T_f<T_{sp}$) quenches. In section \[INCUBATION\] we define the incubation time $\tau_{inc}$ and investigate its dependence on the depth of the quench. Anisotropic scaling functions are discussed in section \[COARSENING\], while section \[SUMMARY\] contains a short summary of our results.

=====================================

We consider a three-dimensional lattice of $L \times L \times L$ fcc–cells with cubic lattice constant $a$ and periodic boundary conditions in all directions. Unless otherwise stated, we use $L=128$. Each site, $i$, of the lattice is occupied either by an atom of type
