摘要: The proportion of low ΣCSL boundaries single phase brass, Ni based Alloy 690, 304 stainless steel and Pb alloy were enhanced to about 70% (according Palumbo–Aust criterion) which mainly Σ3n (n = 1, 2, 3…) types by small amount deformation recrystallization annealing. All the resulting microstructures constituted large size grain-cluster, in all orientation relationships between any two grains (no matter adjacent or not) could be described misorientations according twin chain analyzing. Twin up 8th generation (Σ38) found one such clusters. outer grain-clusters crystallographically random with In case high boundaries, connectivity boundary network was not fragmented obviously when criterion used, whereas substantially interrupted Brandon applied.
