【报告题目】Stabilizing nanostructures in metals

时间: 15:00,NOV.28th, 2017

地点: 科学馆207

摘要:The traditional method for modifying the properties of metals is to alloy them with impurity elements to change their microstructure and/or their phase constitution. Incorporating interfaces into crystalline lattice of metals provides an alternative approach to advancing properties without changing their chemical compositions. Dramatic property variations and unprecedented performances have been discovered in nanostructured materials in which high density interfaces are introduced. Nevertheless, stability of the interfaces at the nano-scale becomes critical for property advancements. Formation of stable interfaces determines stability of nanostructures, and hence is controlling properties and functionalities of nanomaterials. This talk is to review recent developments of stabilization in nanostructured metals. Quantity, structure, composition, and distribution of several types of interfaces are analyzed to identify their effects on properties and performance in nanostructured metals. Perspectives on stabilization of nanostructures in metals are discussed with respect to its future development and technological applications.
