Crystallographic preferred orientation (CPO) develops during plastic deformation as ice deforms dominantly by dislocation glide on the basal plane, modified and often intensified by dynamic recrystallization. CPO patterns in fine-grained …
WebSimple shear is a deformation mode at constant volume, relevant for deformation twinning. For martensitic transformations, a generalized version called invariant plane strain is … WebJan 6, 2024 · Crystallographic shear structures have unique characteristics, and are created by m × n × ∞ ReO 3 -type blocks, where m and n represent the numbers of metal oxide octahedra (MO 6) along the length and width of the blocks, 22, 26 respectively.
WebIn separated planes, the blocks are joined along the c-axis by crystallographic shear edge-sharing. Unlike the ordered Nb 11 WO 33 blocks, the Nb 14 W 3 O 44 blocks are composed of residual WO 4 and all NbO 4 octahedra.
