【摘要】 利用电子背散射衍射(Electron Back Scatter Diffraction-EBSD)技术,对不同退火温度下Fe-32Mn-2Si-4Al孪晶诱发塑性(Twining Induced Plasticity-TWIP)钢冷轧变形后退火再结晶组织的晶界特征、晶粒取向差、织构的变化进行研究。结果表明:随着退火温度的升高,TWIP钢中∑1CSL晶界含量减少,∑3CSL晶界增加,α-取向线和β-取向线密度总体上升,Goss{011}<100>、Copper{112}<111>密度都呈下降趋势,而Brass{011}<211>、S{123}<634>密度呈上升趋势。更多还原

【Abstract】 The grain boundary character distributions(GBCD),the misorientation and the development of recrystallization texture in TWIP steel sheets were investigated by Electron Back Scatter Diffraction(EBSD).The results indicate that with the increase in annealing temperature,∑1 coincidence grain boundary decreases and ∑3 coincidence grain boundary increases,the intensity of β-fiber and α-fiber increase totally.The intensity of Goss{011}<100> and Cu{112}<111> trend weaker,the intensity of S{123}<634>,and Brass{011}<211> trend stronger with the increase in anealing temperature.更多还原
