Advances in Space Research

Based on the non-classical nucleation theory, the size of critical fluctuations, the critical free energy change and the nucleation rate are estimated for the specific case of the precipitation of metastable δ′ ordered phase from a disordered matrix in the AlLi alloy.

Acta Materialia

It is found that the precipitation of δ′ occurs either by a congruent ordering process followed by decomposition, or by a non-classical nucleation mechanism which requires critical fluctuations of both composition and order parameter, except in a narrow range of compositions near the equilibrium phase boundary of the disordered phase, where classical nucleation theory seems to be applicable.

Acta Materialia

Indeed, explorations of the critical fluctuations and time scales at play in ET and PCET are of great general interest.
