AbstractThis paper focused on the interface relationships between primary alpha (alpha(p)) and the precipitation secondary alpha (alpha(s)) phase at different cooling rates from 965 degrees C. The rapid cooling rate favors the precipitation of the secondary alpha(s). And the low cooling rate is conducive to the epitaxial growth of the primary alpha(p). One key finding is that once the grain boundary (alpha(GB)) nucleated on the alpha(p) could grow forward without maintaining the Burgers orientation relationship (BOR) with adjacent beta grains. What's more, HADDF and Fourier-filtered HRTEM images elucidated that two adjacent alpha(p) particles share a common plane but not the same atomic arrangement direction in crystal spatial. Three precipitation types of the alpha(s) were discussed through EBSD and 3D spatial crystalline orientation. Specifically, the as shares common {1 1 2 0} plane with the alpha(p) grains respectively in Type-I and Type-II, but displaying different c axis angle (60 degrees in Type-I and 80 degrees in Type-II). For the Type-III, the secondary as shares common {1 0 1 0} plane with the primary alpha(p), and the angle of c axis between them is 60 degrees. Moreover, the primary alpha(p) do not maintain the BOR with the pre-existing beta, except for Type-I. (C) 2022 The Author(s). Published by Elsevier Ltd.
