The effect of grainboundarystructure on secondary working embrittlement (SWE) of IF steels was studied by electron back-scatter diffraction (EBSD) and TEM.
The individual crystal units comprising the aggregate structure where the crystalline orientation does not change. The grainboundary is where these individual crystal units meet.
构成总的结构的单个的晶体个体,而晶体的方位并没有发生变化。晶界是这些单个的晶体单位相遇的界限。

Imaging with scanning transmission electron microscopy showed that the atomic grain-boundarystructure had dislocations that had very similar arrangement.
