5) sub-grain
亚晶粒
1.
GaN epilayer grown on single buffer layer has poor quality which were investigated by double-crystal X-ray diffraction (DCXRD) and transmission electron microscope (TEM), it can be seen that there are dislocations, inversion domains and sub-grains, while just low density dislocations can be seen in GaN epilayer.
双晶X射线衍射(DCXRD)与透射电子显微镜(TEM)观察发现,单缓冲层上生长的样品晶体质量较差,内部含有位错、反畴区和亚晶粒等缺陷,而双缓冲层上生长的GaN只含有较低密度的位错,说明双缓冲层有效地降低了缺陷密度。
6) subgrain
亚晶粒

It is sure that there are a lot of subgrains in some sections of the tube, which is the basic cause of bringing about that the tube colour turns into the black, through the investigation and the simulation test to the macrostructure characteristics of the tube, the fonnation mechanism about the subgrains and the methods to eliminate them are explained.
7A04CS合金管材阳极氧化后颜色不均匀,通过对管材组织特征的观察和模拟试验,确定管材中某些部位存在大量的亚晶粒,它是造成颜色发黑的根本原因。

It was shown that the subgrains are well formed and the size decrease withincreasing of rolling pass.
参照美国一铝业公司热轧工艺规程，在Ｇｌｅｅｂｌｅ－１５００热模拟机上，对工业纯铝多道次热轧过程进行了实验模拟，通过对变形后试样组织的金相与ＴＥＭ观察及显微硬度测量，发现亚晶粒随着道次增加逐渐形成完善，其尺寸逐渐变小；再结晶不仅取决于轧制温度，而且还与变形不均匀带，累积变形量及道次间停留时间有关；在试样厚度较大的某些道次，发生再结晶的位置交替地由高向两侧转向中心部位。
补充资料：晶粒
grain：多晶体金属材料内的每个晶体，由于它们在形核后的长大过程中都受到相邻的、也在长大着的晶体的妨碍，以致都不能在三维空间自由地长大，所以最后长到相互接触时都没有规则的外形，故称晶粒。
