摘　　要：材料是物理性能的产生及能量相互转换的重要载体,材料结晶是新材料创制的核心和探索的前沿方向.多尺度材料结晶是相关领域研究人员共同面临的科学问题.材料结晶模型是以相图为基础,确定材料的组成与相关物理化学参数,结合材料结晶理论和生长方法共同构建材料结晶.本文综述了从成核到生长的主要理论与部分材料结晶生长方法,指出材料结晶研究向着多尺度、多因素、定量化的方向发展.材料结晶设备向着自动化、数字化、智能化方向发展.材料结晶研究了多尺度的相演变过程,包含从成核到生长的质量与能量传递过程,需要多学科交叉领域的协同发展.The generation of physical properties and energy conversion takes place in materials,and material crystallization is the core of new material creation and frontier direction of exploration.Multi-scale material crystallization is a common scientific challenge faced by researchers in many fields.Material crystallization models are based on corresponding phase diagrams such that the material composition and related physical and chemical parameters can be determined and combined with material crystallization theory and growth methods to realize material crystallization.In this paper,the main theories from nucleation to growth and crystallization growth methods of some materials are reviewed;research on material crystallization is developing toward multi-scale,multi-factor,and quantification.Material crystallization equipment is progressing toward automation,digitalization,and intelligentization.Material crystallization studies focus on multi-scale phase evolution,including the mass and energy transfer process from nucleation to growth that requires the coordinated collaboration of multidisciplinary fields.
