一、建立材料性能数据库的必要性五十年代以来,我国航空材料性能试验研究工作发展迅速。性能测试从单一的为材料、工艺提供数据,进而作为强度研究、寿命预测的重要依据,应用范围日益扩大。至今已积累了大量常规数据和特殊性能数据,在实践中培养了一支有相当水平的专业队伍。随着航空工业的发展,飞机及发动机设计、改型、更新换代、维护检修等,对材料性能提出了更多更高的要求。设计部门要求提供接近构件实际工作条件下的性能数据迫在眉睫。航 First, the need to establish the database of material properties Since the 1950s, China’s aviation materials performance test research is developing rapidly. Performance testing from a single material, technology to provide data, and then as an important basis for strength studies, life prediction, the growing range of applications. So far, a large amount of routine data and special performance data have been accumulated, and in practice a considerable number of professional teams have been trained. With the development of the aviation industry, aircraft and engine design, modification, upgrading, maintenance and repair, etc., put forward more and higher requirements on the material performance. It is imperative for the design department to provide performance data that is close to the actual operating conditions of the component. Air
