题目：报告1：Development of characterization techniques for materials

报告2：Optimization of structure and properties of nanostructured metals

摘要：

(1) Progress of materials science relies on the development of new characterization techniques and new understanding of the structure-property relationships. Over the last decades, global wide effects have been made to develop techniques for 2D and 3D mapping of crystallographic orientation, which is the most important parameter determining the behavior of plastic deformation and phase transformation of both conventional coarse-grained and nanocrystalline materials. In this presentation, the orientation measurement techniques developed at Riso DTU based on X-ray diffraction and electron diffraction is introduced.

(2) The 3D characterization examples are given to demonstrate how detailed characterization of the structural parameters has led to (i) new understanding of the strengthening mechanisms and the flow instabilities in nanostructured metals, (ii) new finding of unusual mechanical behaviors such as annealing-induced hardening and deformation-induced softening, and (iii) new suggestion of strategies for structure and property optimization.
