Modeling of whole process of ageing precipitation and strengthening in Al-Cu-Mg-Ag alloys with high Cu-to-Mg mass ratio HOU Yan-hui(侯延辉)1, 2, 3, GU Yan-xia(谷艳霞)1, 2, LIU Zhi-yi (刘志义)1, 2, LI Yun...-Cu-Mg-Ag alloys during the whole ageing process was developed. A thermodynamically-based precipitation model, employing the classical nucleation and growth theories, was adapted to deal......
of the objective function. The results show that the proposed inversion method has a higher location accuracy than the traditional algorithm for both internal field source and external field source. The former.... The research results may offer reference for location analysis in the similar projects using the micro-seismic observation system. Key words: minimal error principle; location algorithm; accuracy......
