材料设计：材料科学的发展趋势

材料设计的提出是材料科学发展的一个里程碑，是材料科学方法论的一次革命．本文讨论材料设计的概念，材料设计的各个组成部分及其相互关系，材料设计的发展现状，材料设计前景展望等．材料设计的基础是材料物性数据库，材料设计的理论和模型需用量子化学、固体物理和宏观系统工程知识．现代微观分析技术和人工智能计算机的发展使材料设计真正成为可能．梯度功能材料的发展是材料设计成功的一个实例．材料设计的发展必将大大缩短新材料的研制周期，从而带来巨大的社会、经济效益．

MATERIALS DESIGN:THE TREND OF MATERIALS SCIENCE

aterials design is a revolution in the methodology of materials science. This paper presents the concept of materials design, the components of materials design and the relationship between them, the recent progress and prospects of materials design. The basis of materials design is the database about properties of materials. The theories and models of materials design span the spectrum of needed processes from the system performance level to the electronic level.The development of theories, modern analytical technology and super-computers will make materials design a real possibility within our generation. The functionally gradient material is a successful example of materials design. Materials design can shorten the cycle of research and development of materials, bringing great economic benefits.
