研究了Fe-Mn-C系TWIP钢的微观组织特征.结果表明,钢板经热处理后.其室温组织为单相奥氏体基体并伴有退火孪晶,同时基体中存在退火孪晶和层错,其退火孪晶量达16.2%,由于锰含量较高在该系列钢中存在锰的偏析行为.
研究瞭Fe-Mn-C繫TWIP鋼的微觀組織特徵.結果錶明,鋼闆經熱處理後.其室溫組織為單相奧氏體基體併伴有退火孿晶,同時基體中存在退火孿晶和層錯,其退火孿晶量達16.2%,由于錳含量較高在該繫列鋼中存在錳的偏析行為.

The microstructure characteristic of twinning induced plasticity(TWIP)steel of Fe-Mn-C system was investigated.The results show that,after hot-rolling and cold-rolling heat treatment,the microstructure is composed of austenitie matrix and annealed twins at room temperature;at the same time,stacking fault is observed by TEM,there ale 16.2%annealing twins observed by EBSD.There is segregation of Mn in the austenitic matrix as a result ofhigh content Mn.
