The results show that Widmansttten structure needle consists of many blocky subgrains that have higher dislocation density and subgrainboundary is made up of dislocation tangle.
结果表明,魏氏组织针由多个块状的亚晶粒组成,亚晶粒边界由位错缠结而成,在亚晶粒内有较高的位错密度;

It is shown from TEM analysis that the fine grained matrix materials are mainly derived from the huge clasts by subgrain rotation and local grain boundary migration.
