The Al-Li damage tolerant alloys now becoming available do not cover the whole range of properties required by the aircraft industry; for successful application on aerospace structures in the future, a full understanding of the material behavior will be necessary. Therefore a development program was initiated in 1990 by the European airframe industry and aerospace institutes with the following objectives: improving the properties of existing alloys as compared to conventional alloys; and evaluating the existing damage tolerant Al-Li alloys from a fundamental point of view, giving confidence in terms of all safety and reliability aspects for real aircraft applications. A survey of this project and some initial results are presented.
