Significant efforts have been made in attempts to understand the crack-tip deformation behavior in metals during tensile deformation in an electron microscope. It is found that deformation occurs mostly by the emission of dislocations from the crack tip, which acts as a possible dislocation source because it is associated with the highest stress. ¡¾·Òë¡¿ÀûÓõç×ÓÏÔ΢¾µÊÔͼÁ˽â½ðÊôÔÚÀÉì±äÐιý³ÌÖеÄÁÑÎÆ¼â¶Ë±äÐÎÐÐΪ£¬£¨Ñо¿ÈËÔ±£©ÒѾ×öÁË´óÁ¿µÄ¹¤×÷¡£½á¹û±íÃ÷£¬±äÐÎÖ÷Òª·¢ÉúÔÚÁÑÎÆ¼â¶ËµÄλ´í·¢É䣬ÕâÊÇÒ»¸ö¿ÉÄܵÄλ´íÔ´£¬ÒòΪËüÓë×î¸ßµÄÓ¦Á¦Óйء£ |
