FOR 544: Mechanical Properties and Interfaces in Ultrafine Grained Materials

点击翻译按钮获取中文摘要

Ultrafine grained (UFG) materials are attractive for many structural applications because of their interesting mechanical properties as compared with conventional materials. However, the lack of validated models appears to be one of the key roadblocks to the widespread use of these materials. Thus, the Research Unit aims at developing microstructurally based models that allow for prediction of the mechanical behaviour of UFG materials. The research will cover different alloys and production methods and employ detailed mechanical and microstructural characterisation studies in order to establish a thorough understanding of microstructure-property-relationships in UFG materials. Such a broad research programme is necessary to be able to develop validated models that can be applied to UFG materials with substantially different stress-strain behaviour and damage mechanisms.
