摘要：

The coarsening of alpha-Fe particles in a Cu-Fe alloy was examined. Using the Lifshitz-Slyozov-Wagner (LSW) theory of Ostwald ripening, the interfacial energy between alpha-Fe and Cu was estimated to be 3.3 J/m2. A coarsening process was also studied when alpha- and gamma-Fe particles coexisted. This coarsening mode was different from that of the usual Ostwald ripening. When the coarsening processes of alpha- and gamma-Fe particles were followed separately, however, the growth and shrinkage of the Fe particle can be understood from the LSW theory.
