As a result of CA-DRX simulations with grain deformation, it was clarified that, from microstructure evolutions, the appropriate deformation during DRX can be reproduced by the developed model. However, it was also concluded that the macroscopic stress¨Cstrain relationship and variations in grain size are not affected by the grain deformation introduced here. Furthermore, the DRX cycle was defined and the relationship between the DRX cycle fraction and the stress¨Cstrain curve was discussed. As a result, it was concluded that the stress¨Cstrain curve with multiple peaks is observed when the strain at the first valley of the stress¨Cstrain curve is smaller than that corresponding to the maximum first DRX cycle fraction. ·Ò룺´Ó¿¼ÂǾ§Á£±äÐεÄCA-DRXÄ£ÄâµÄ΢¹Û½á¹¹µÄÑÝ»¯½á¹û¿ÉÒÔÈ·ÈÏ£¬ÔÚDRX¹ý³ÌÖнüËÆµÄ±äÐλᱻ·¢Õ¹µÄÄ£ÐÍËùÈ¡´ú¡£È»¶ø£¬ºê¹ÛÓ¦Á¦¡ªÓ¦±äÇúÏß¹ØÏµºÍ¾§Á£³ß´ç±äÁ¿²»Êܾ§Á£±äÐεÄÓ°Ïì¡£ÁíÍ⣬¶¨ÒåÁËDRXÑ»·£¬²¢ÌÖÂÛÁËDRXÑ»··ÖÊýºÍÓ¦Á¦¡ªÓ¦±äÇúÏߵĹØÏµ¡£½á¹û£¬µ±Ó¦Á¦¡ªÓ¦±äÇúÏߵĵÚÒ»¸ö¹ÈµÄÓ¦±äСÓÚ×î´óµÚÒ»´ÎDRXÑ»··ÖÊý¶ÔÓ¦µÄÓ¦±äµÄʱºò£¬¿ÉÒԹ۲쵽¶à·åÓ¦Á¦¡ªÓ¦±äÇúÏß¡£ ÎÊÌ⣺·ÒëµÃ²»ºÃ£¬ÇëÏà¹Ø×¨ÒµµÄ¸ßÊÖ°ïÈóÉ«£¬Ð»Ð»¡£ |
