“…Motozuka et al investigated the microstructural changes caused in Fe particles with bcc crystal structure by ball milling. [15][16][17] Ball milling is an SPD process and it induces a huge strain by mixing Fe particles and hard particles with relatively large diameters. Their studies showed that the Fe particle shape changes from granular to platelet during ball milling, and the grains in the Fe particles are highly refined.…”

The crystallographic texture of pure Cu formed by shot peening (SP) and the texture formation process are investigated. When a pure Cu sheet with a β‐fiber texture is subjected to SP, grain refinement occurs and a deformation‐induced layer is formed around the peened surface. The crystal lattice is rotated and a {110} fiber texture, in which the ⟨110⟩ direction is parallel to the plane normal direction of the peened surface, is formed. The intensity of the {110} fiber texture increases with increasing SP duration. The {110} fiber texture is formed by uniaxial compression for face‐centered cubic metals. It is concluded that uniaxial compression is dominant in deformation by SP and a {110} fiber texture is therefore formed. Moreover, using shot‐peened (SPed) specimen with {110} fiber texture, a growth test of graphene is carried out. The SPed specimen is used as a substrate to grow the graphene by the chemical vapor deposition process. Growth of high‐quality graphene on the SPed specimen is obtained compared to unprocessed substrate surface. Therefore, control of the crystallographic texture by SP would be one of important tools for preparing Cu and other catalytic substrate surfaces for high‐quality graphene growth.
