Triple junctions are linear defects along which three grain boundaries meet. They exhibit thermodynamic properties unique from those of their constituent grain boundaries. Triple junctions can act as short circuit diffusion paths, serve as preferential sites for the nucleation of new phases, cavities and corrosion, play an important role in plastic deformation, etc. ¡¾·Òë¡¿£ºÈý²æ¾§½çÊÇÈýÌõ¾§½çÏàÓöʱµÄÏßȱÏÝ£¬Æä±íÏÖ³ö¶ÀÌØµÄÈÈÁ¦Ñ§ÐÔÖÊfrom those of their constituent grain boundaries¡£Èý²æ¾§½çÄܹ»³äµ±¶Ì·À©É¢Í¨µÀ£¬³ÉΪÐÂÏàÐκˡ¢¿Õ¶´ºÍ¸¯Ê´µÄÓÅÏÈλÖã¬ÔÚËÜÐÔ±äÐιý³ÌÖÐÆðÖØÒª×÷Óõȡ£ ±¸×¢£ºgrain boundaries £º¾§½ç |
