摘要
研究了合金钢中马氏体的晶体结构和其实际固溶碳量的关系。针对Kurdjumov公式的不足,通过X射线衍射并采用新的分析方法建立了可精确测定钢中α相含碳量的经验方程,首次用该方程测出了贝氏体铁素体中的过饱和碳量。论证了贝氏体铁素体在含碳量小于0.3％时为体心立方结构,碳量大于0.3％后呈体心正方结构。
The relationship between carbon content in martensite and its crystal lattice were systematically studied in alloy steels. An empirical formula, which can be used to accurately determine the carbon content in a phase in steels, was obtained using X-ray diffraction and a new analyzing method. Using this formula the supersaturated carbon content in bainitic ferrite has been first determined. The bainitic ferrite is BCC lattice when the carbon content in it is below 0.3％ and it is BCT lattice when the carbon content is over 0.3％.
