Texture Analysis of Copper Using Neutron Diffraction Technique

Texture analysis of copper have been performed using neutron diffraction technique. For neutron diffraction experiment, a copper sample are formed into three types, Cu-freely powder with grain size ≤100 mesh obtained by grinding the Cu-rod sample, Cu-bulk powder which is obtained from pressing the freely powder and a Cu-rod as the original sample. From crystal structure analysis, it is obtained that preferred orientation occur due to rolling. For Cu-freely powder sample and Cu-bulk powder, crystallite distribution are random with highest intensity at (111), whereas Cu-rod highest intensity appears at (220). From pole figures of (111), (200) and (220), it is shown that rod axis of the sample is parallel to and fiber textures appear as duplex component at and directions. Maximum orientation distribution density is 3.37 m.r.d (multiple of a random distribution)
