Preface to the special issue on ultrafine-grained materials

摘要

This issue is the fifth in a series of special issues on ultrafine-grained (UFG) materials to be published in the Journal of Materials Science. The scientific studies collected here represent selected papers from the Eighth International Symposium on Ultrafine-Grained Materials (UFG VIII), which was held in San Diego, CA, USA from February 16-20, 2014. The eighth UFG symposium was one of the largest symposia at the 2014 TMS Annual Meeting and Exhibition and consisted of 158 abstracts from 20 countries.
