学术报告1

题  目:Microstructure and strength of deformed metals from the macro to the nanoscale

报告人:Niels Hansen 教授

时  间:2016年10月19日9:00-10:00

地  点:世纪楼18层报告厅

摘  要:Plastic deformation processes refine the microstructure of metals and the finer the structure the stronger the metal. Close links therefore exist between processing, microstructure and strength of metallic materials. The deformed microstructure is central and its evolution with increasing strain must be characterized and structural parameters must be quantified. Such parameters determine the strength and are the basis for the formulation of strength-structure-strain relationships or constitutive equations to be used in analytical and numerical models. Such models are in global demand to guide design of processes and materials for a wide range of applications where examples are strong and light metals and surface engineering.

学术报告2

题  目:Recrystallization Kinetics and Relations to Mechanical Properties

报告人:Dorte Juul Jensen 教授

时  间:2016年10月19日10:00-11:00

地  点:世纪楼18层报告厅

摘  要:When a deformed metal is annealed, it typically recrystallizes whereby the metal becomes softer and more formable. Although this is very well known and has been used extensively in practice, key questions concerning the recrystallization mechanisms remain unsolved. Furthermore, new experimental characterization, for example in 4D by synchrotron x-ray diffraction, has revealed that well-accepted theories cannot explain the new data. In this presentation, the potentials of various experimental techniques for characterization of recrystallization are discussed and examples are given of key questions studied by these techniques. It will be shown how the techniques complement each other and have brought new understanding of recrystallization. Finally, the importance of local microstructural variations for the relations between recrystallization kinetics and mechanical properties are discussed.
