The future lies in a better understanding of the relation between grain boundary structures and their behavior under stress. Detailed knowledge of the relation between grain boundary structure and its mechanical behavior will allow the design of sophisticated microstructures and will lead to synthesis methods that produce improved grain boundary structures. ·Ò룺 ¾¡¹ÜÓÐÆä¾ÖÏÞÐÔ£¬µ«´ÓÔ×ӳ߶ÈÄ£Äâ½Ç¶È¶ÔÖ¸µ¼ºÍÀí½âʵÑé½á¹ûÓзdz£ÖØÒªµÄ¼ÛÖµ¡£½«À´¶Ô¾§½ç½á¹¹ºÍÆäÔÚÓ¦Á¦ÏµÄÐÔÄܽ«»áÓиüÉî¿ÌµÄÀí½â¡£¶Ô¾§½ç½á¹¹ÒÔ¼°ÆäÁ¦Ñ§ÐÔÄܹØÏµµÄÏêϸÁ˽⽫ΪÉè¼Æ¸ü¸´ÔÓµÄ΢½á¹¹ºÍ¹¹Ôì¸ÄÁ¼¾§½ç½á¹¹µÄºÏ³É·½·¨Ìṩ±£ÕÏ¡£ ¶þ No direct experimental visualization technique is available that allows nonintrusive investigation of grain boundary structures during deformation.
