Study of nano spatiotemporal dynamics on phase transformation in advanced materials by in situ observation technique

在本研究中，我们进行了开发，纳米时空动力学原位观测实验装置，将在燃料芯块靶区激光惯性约束聚变反应的皮科现象测量中取得许多成功结果的条纹相机和各种高速CCD相机结合起来，以便找到唯一剩下的问题的解决方案，以改善时间分辨率，并将TEM的记录时间从2009财年延长至2011财年。我们将新研制的实验装置安装到我们现有的透射电镜上，通过纳米时空分辨率的记录，研究了电子辐照和离子辐照下接头界面处的裂纹萌生点或多裂纹扩展，揭示了高速扩展的多裂纹路径与纳米级缺陷之间的相互作用。

In this study, we carried out the development of in-situ observation experimental apparatus on nano spatiotemporal dynamics to combine the streak camera which had many successful results of the measurements in pico second phenomena on the laser inertial confinement fusion reaction at the target region of the fuel pellets and the various high speed CCD cameras in order to find out a solution of the only remaining issues to improve the temporal resolution and extend the recording time in TEM for three years from FY2009 to FY2011. We installed the newly developed experimental apparatus to our present TEM and investigate the crack initiation point or the multi crack propagation at the interface of the joint under electron irradiation and ion irradiation by recording in nano spatiotemporal resolution where so far it has not been done by us, and revealed the interaction between the multi crack paths which grew in high speed and nano sized defects.
