选材系统的设计与实现

介绍一个基于材料科学数据库的选材系统。该系统按照开放性的原则设计，将材料科学数据分为三大部分：仅与材料成分有关的基本材料数据，材料加工和应用过程中产生的材料加工工艺和性能数据，材料产品的生产供应等商业信息。

Computer Aided Material Selection System

A new material selector,based on material scientific database,is introduced. This system is designed under the rule of expandable structure.By analyzing the concepts in ma- terial science and technology,the material database is cut into three parts:basic material data which only depend on the composition,process parameters and properties involved in materials processing,and commercial information about material products. Through registering the process parameters and properties of material application systems into materials scientific database,the re- lationship between material,process and properties is established,and therefore it comes into re- ality that the engineers can simultaneously select materials and planning the process.And this laid a solid foundation for this system to become a supporting material selection system for CAD/ CAE/ CAM/ CIMS software packages.
