【摘要】 利用光学显微镜、扫描电镜、X射线分析仪和透射电镜,研究了硼(B)含量在0.1%～1.0%和碳(C)含量0.6%～0.8%的铸造高硼钢的凝固组织。结果表明,高硼钢的凝固组织由FeB、铁素体、珠光体和板条马氏体及贝氏体组成,硼碳化物呈网状沿晶界分布。更多还原

【Abstract】 The solidified microstructures of high B steel containing 0.1%~1.0% B and 0.6%~0.8% C was investigated by means of optical microscopy (OM),scanning electron microscopy (SEM),X-ray diffraction (XRD) and transmission electron microscope (TEM). The results show that the solidified high-B steel consists of boride (FeB),ferrite,pearlite,martensite,and bainite. And boride revealed network in shape distributes along grain boundaries.更多还原
