Textural and microstructural evolution during cold-rolling of pure nickel.

摘要

High purity nickel (99.99%) with a grain size about 100 (mu)m has been deformed by cold-rolling from 37% to 98% reductions. The deformation microstructures and the crystallographic texture have been characterized using transmission electron microscopy and neutron diffraction, respectively. The microstructural evolution has been described within a general framework which consists of a grain subdivision by dislocation boundaries on a finer and finer scale with increasing strain. The influence of this deformation pattern on the texture development is discussed.
