Grain orientation effects in Zr702α polycrystalline samples deformed in channel die compression at room temperature

摘要: Abstract Deformation mechanisms are determined in five zirconium polycrystalline samples deformed by channel die compression at room temperature (T1–T5 textures). Slip systems characterized a slip trace analysis and twinning misorientation calculation between twinned non-twinned parts of the grains, from Electron Back Scattering Diffraction (EBSD) measurements. The is completed measurement crystallographic texture evolutions examination stress–strain curves. Prismatic glide {10 1 2} identified as primary deformation modes first-order pyramidal 1} basal secondary modes. experimental study numerical approach using models which consistent with observations.
