چکیده انگلیسی
Fully recrystallized Zircaloy 2 samples were made in two dominant classes of crystallographic orientations: grains with predominantly (I) basal (ã0Â 0Â 0Â 1ã) and (II) non-basal plane-normal. The present study charted out detailed microstructural developments, of both the samples, during uniaxial cold compression. Sample I showed insignificant twinning and had stronger signatures (in-grain misorientation and estimated values of lattice strain and dislocation densities) for slip; while sample II had both slip and twin and substantial modifications in crystallographic texture. Strong heterogeneity in residual stress was observed between the suspected parent and product grains/orientations of twinning. This effect could be captured, effectively, with a simple geometric model based on anisotropic elastic stiffness.
