摘要
主要以经典理论,即二元合金spinodal分解的热力学判据:2G/C2<0为基础,简介spinodal分解的一般概念、理论和动力学。强调指出:spinodal分解的经典理论也面临由B inder等提出新概念的强烈挑战,即形核-长大机制与spinodal分解是连续变化的;以及B inder等思想的重要性。对spinodal一词的来源作简单的论述。
The general concept,theory and kinetics of spinodal decomposition are elementally introduced mainly based on the classical theory,i.e.,the thermodynamics criterion of spinodal decomposition in binary alloys is 2G/C20.It is emphasized to point out that the classical theory of spinodal decomposition is now facing a forceful challenge made by the new idea of Binder et al.that there is a continuous variation between nucleation growth mechanism and spinodal decomposition and the importance of his thought.The origin of spinodal name is simply discussed.
