作者讨论了界面性质，特别是界面能σ和迁移率μ在一系列固相反应中的作用，这些反应涉及第二相沉淀物的尺寸和形状的变化。以下主题进行了讨论：（一）从过饱和固溶体的沉淀物生长;（二）竞争性增长的沉淀物，以减少其界面能，奥斯特瓦尔德熟化;和（iii）迁移的高角度矩阵晶界通过分散的相干沉淀物。
The author discusses the role of interfacial properties, notably interfacial energy σ and mobility μ, in a series of solid-state reactions that involve the change of size and shape of second-phase precipitates. The following topics are discussed: (i) precipitate growth from a supersaturated solid solution; (ii) competitive growth of precipitates to reduce their interfacial energy, Ostwald ripening; and (iii) migration of a high-angle matrix grain boundary through a dispersion of coherent precipitates.
