摘要
利用光学显微镜和透射电子显微镜详细研究了在不同应变量下 ,形变诱导铁素体的微观组织结构·结果表明 :形变诱导铁素体的形态与正常退火的相似 ,而尺寸明显细化 ;在应变速率一定的条件下 ,形变诱导铁素体的量增加主要是形变诱导的作用 。
Microstructures of deformation induced ferrite under the conditions of various strains at 780?℃ with 1?s -1 strain rate were investigated by means of optical microscopy and transmission electron microscopy. The influence of strains on the amount and size of deformation induced ferrite was discussed. Results show that morphology of deformation induced ferrite is similar to that of normal annealing ferrite, and the size of deformation induced ferrite is obviously decreased. The increase in amount of the deformation induced ferrite is due to deformation enhancement in phase transformation. The decrease in size of deformation induced ferrite is due to the enhancement of recrystallization.
