Severe plastic deformation is a kind of technology making ultra-fine microstructure. The copper of purity 99.99% subjected to equal channel angular pressing was examined by neutron diffraction and EBSD measurement. Dislocation density and grain size were determined by the Williamson-Hall and the integral breadth method. Dislocation density increased first, but decrease afterwards. Grain size becomes the smallest to around 500nm with processing. Because of the neutron diffraction the profile analysis could evaluate dislocation density relatively, but reliability was low in grain size.
