【摘要】 利用场发射电子显微镜的EBSD与EDS联用功能对低合金高强钢中析出的第二相的结构进行了标定,结果为Nb、Ti的碳化物、氮化物和碳氮化物。通过水系电解法提取出基体中析出的第二相,并通过XRD和TEM的EDS确定其结构亦为Nb、Ti的碳化物、氮化物和碳氮化物,与EBSD实验的结果互相吻合,证明了分析结果的正确性。更多还原

【Abstract】 The structures of second phase precipitations of HSLA steel were calibrated.The results were carbide,nitride and carbonitride of Nb,Ti.The function of combination of EBSD and EDS of field emission scanning electron microscopy was used.The second phase precipitations were extracted from the matrix by the electrolytic process of water system,which were detected by XRD and EDS of TEM.The structures of the second phase precipitation were also carbide,nitride and carbonitride of Nb,Ti.The results were consistent with EBSD and the correctness of the results was proved.更多还原
