二元互不溶体系中第二相颗粒的Ostwald熟化∗

摘要

二元互不溶体系是具有重要工程技术价值的材料。综述了近年来二元互不溶体系中第二相颗粒的Ostwald熟化的研究进展，简述了 Ostwald 熟化的经典理论———LSW理论和现代 Ostwald 熟化理论，着重介绍了二元互不溶体系中第二相颗粒的 Ostwald熟化以及第二相体积分数、颗粒形状和合金元素的影响。%Binary immiscible systems are materials with vital engineering value.Herein the Ostwald ripening of secondary phase particles in binary immiscible systems is overviewed,and the classical Ostwald ripening theories inclu-ding LSW theory and modern Ostwald ripening theories are also addressed,with focus on the Ostwald ripening of se-condary phase particles in binary immiscible systems and the influencing factors,such as volume fraction of secondary phase,particle morphology,alloy elements.
