摘要
颗粒增强金属基复合材料具有高模量、高强度及高耐磨等优异性能,其材料体系庞杂、复合结构繁复,力学性能指标众多。通过结构建模与力学模拟的系统研究,能够有效揭示复合材料的构效关系与组织演变规律,进而指导其设计、制备、加工与应用全流程研究。开展多尺度建模计算,并与宏、微观实验相融合,以及利用以数据库技术、高通量计算与大数据挖掘为主要特征的材料信息学研究,可实现金属基复合材料的“组分-工艺-结构-性能”内禀关系的科学内涵描述。首先回顾了颗粒增强金属基复合材料建模计算的主要研究方法,然后对其结构建模研究现状进行了介绍,进而围绕界面特性与力学模拟进行了综合述评,最后对建模拟实结合材料基因工程技术的未来发展进行了展望。
Particle reinforced metal matrix composites(PRMMCs)possess excellent mechanical properties such as high modulus,high strength and high abrasion resistance,which own to the complicated material systems,complex composite structures and numerous mechanical property indexes.Through the quantitative and systematical investigations of structural modelling as well as mechanical simulation,the structure-property relationship and microstructure evolution in PRMMCs can be figured out,thus providing guidance to the overall research on materials design,preparation,processing and application.Based on the multi-scale materials computation and macro-/microscopic experimental tests,combining with material information research containing database technology,high-throughput computing and big data mining,it can be carried out to indicate the scientific description over the intrinsic relevance among composition,processing,structure and property of PRMMCs.In this paper,the common research approaches related to the structural modelling and property simulation of PRMMCs are firstly reviewed,while the research progress of structural modelling of PRMMCs is subsequently introduced.Afterwards,the current achievements on interfacial characterization and mechanical simulation of PRMMCs are summarized.Finally,an outlook to the future of modelling&simulation of PRMMCs combining Materials Genome Initiative is proposed.
