Webthe relative areas of grain boundaries with distinct grain boundary plane normals and misorientations, and may be defined in units of multiples of a random distribution (MRD) [2]. The GBED describes the relative energies of these boundaries, and can be expressed in relative arbitrary units (a.u.), or units of energy if a reference value exists. WebFeb 15, 2024 · Fig. 1 presents the grain boundary map for samples treated by solution annealing, GBE processing, and post-GBE aging treatment. In this figure, green, red, blue, aqua, and black lines indicate Σ1, Σ3, Σ9, Σ27, and random HAGBs, respectively. Special boundaries (3 = Σ ≤ 29) other than Σ3, Σ9, and Σ27 have been shown in yellow color.
WebDec 1, 2014 · The central grain contains a low angle boundary with disorientation angles varying from 1.4° to 3.2°. This boundary appears as clearly on the KPQ map as the 17°-boundary indicated in Fig. 1 b. This confirms the sensitivity of the KPQ to low angle disorientation boundaries as reported in [9].
