英文摘要：

The studies on GBCD optimization technology of face-centered cubic metal in recent years were summarized. The domestic and foreign research results were introduced by three aspects,which included the technology process and influence factors to improve low ΣCSL grain boundary proportion,the formation mechanism of low ΣCSL grain boundary and the influence mechanism of low ΣCSL grain boundary proportion on the properties of the face-centered cubic metal. Some of these parameters and the theories were explained and discussed.Finally,some questions to be solved in future are proposed.
