Nucleation and growth of γ′-Precipitates in Ni-14 at.% Al
TL;DR: In this article, atomic probe field-ion microscopy has been used to study the decomposition of Ni-14 during isothermal aging at 823 K. The observed decomposition behaviour is interpreted in terms of the classical nucleation theory and by a modification of a theory due to Langer and Schwartz which considers coarsening already during the nucleation stage.

Reactive spreading: adsorption, ridging and compound formation
TL;DR: In this paper, a chemically active element is added to promote wetting of noble metals on nonmetallic materials, and a theory for the energetics and kinetics of the necessary steps involved in spreading is presented.
