Abstract

Various orientations and diffraction patterns of metastable β″ precipitates during artificial aging are investigated by means of high-resolution electron microscopy and electron diffraction in Al-Mg-Si alloys. Twelve orientations of β″ precipitates with C-centered monoclinic crystal structure are analyzed systematically. The orientation relationships can be expressed as: (0 1 0)_β″//{1 0 0}_Al; [0 01 ]_β″//<3 1 0>_Al; [1 0 0]_β″//<2 3 0>_Al. In addition, a new diffraction patterns model from β″ precipitates in 12 orientations is established under the [0 0 1]_Al zone axis.
