Of decent education,
Determine all-important truths,
With strange precipitation.

Grew jealous of her: with precipitate feet,
As loth to wrong them unawares, she fled.

These dim snatches of her chant
Only have remain-ed mine;--

Revives, refreshes and invigorates

Each blade of grass and floweret with a tear;
As nature, weeping o'er the faults of man.

A sudden gleam divine, precipitating, bursting all these bubbles,
fashions, wealth?

To utter nothingness?

For the maximum precipitate density dmax , these dependencies shown in Figs. 13 and 15 are mainly determined by the reduced supersaturation s (defined in Eq. (2) and Table 1) which characterizes the scale of the thermodynamic driving force for precipitation.
Studies of concentration and temperature dependencies of precipitation kinetics in iron-copper alloys using kinetic monte carlo and stochastic statistical simulations
The temporal characteristics of precipitation shown in Figs. 14 and 16b decrease with increasing supersaturation s, which can be explained by an increase of the thermodynamic driving force.

It is true not only for the coarsening stage (for which a great difference in the precipitate sizes is natural as the bigger precipitates coarsen due to dissolving the smaller ones) but also for all other stages of precipitation.

We see that the great ma jority of precipitates at t=1.1 tmax still continue to grow due to the absorption of copper atoms from the matrix, even though some smallest precipitates already start to dissolve.

Third, Fig. 17 shows that the precipitate size distribution νk (t) for the state G with the highest temperature T =873 K is, generally, much more uniform than νk (t) for the states B and D with the lower T =773 K and 713 K, particularly for the early coarsening stage, which is illustrated by frames G4, B4 and D4.

This difference can be related to the weakening of the vacancy-copper atom correlations at high T which can enhance the copper diffusivity DCu and thereby promote growth of many big precipitates for the state G unlike the states A, B and D , but these points need further studies.

As supersaturation s and the precipitate density dp for this state are rather low, these simulations are time-consuming and include only nucleation and growth stages, while the data by Shabadi et al. seem to correspond to the longer aging times and have significant errors.

Within these errors, the simulation and experimental results in Fig. 12 can be considered as agreeing with each other, particularly for the maximum precipitate density dmax , though the simulated evolution times can be somewhat shorter than the observed ones.
