As the temperature increases, the incipient duration of the partial dislocation nucleation becomes longer, the critical stress intensity factor for partial dislocation emission is reduced and, at the same loading level, more dislocations are emitted. The dislocation velocity moving away from the crack tip and the separations of partial dislocations are apparently not temperature dependent. ¡¾·Òë¡¿Ëæ×ÅζȵÄÉý¸ß£¬²»È«Î»´í³ÉºËµÄÔÐÓýÆÚ±ä³¤£¬²»È«Î»´í·¢ÉäµÄÁÙ½çÓ¦Á¦Ç¿¶ÈÒò×Ó¼õС£¬ÔÚÏàͬµÄ¼ÓÔØÌõ¼þÏ£¬·¢ÉäµÄλ´í¸ü¶à¡£ λ´íÔ¶ÀëÁѼâµÄËٶȺͲ»È«Î»´íµÄ·ÖÀëËÙ¶ÈÏÔÈ»ÊDz»ÒÀÀµÓÚζȡ£ רҵÃû´Ê£ºpartial dislocation ²»È«Î»´í |

With the increaseing of temperature ,the incipient duration of the partial dislocation nucleation is lengthening, And the critical stress intensity factor for partial dislocation emission is decreaseing. There are more dislocations emitting at the same level.It indicates that dislocation velocity moving away from the crack tip and the separations of partial dislocations are apparently not temperature dependent.
