摘要
介绍了彩色金相的显示原理、方法及在其显微组织分析中的应用,对比了双相钢、帘线钢彩色金相和黑白金相的显微组织颜色、形貌及定量计算结果。结果表明:彩色金相因其具有艳丽的色彩、强烈的对比度,可以明显辨识出双相钢、帘线钢各相显微组织,双相钢的铁素体组织呈浅黄色、马氏体和残余奥氏体呈亮白色、贝氏体呈棕黑色,帘线钢的珠光体呈亮白色,索氏体呈蓝、黑、棕、灰白等色,并能够计算出各相显微组织的面积分数,进而实现定量分析,其分析精度远高于传统黑白金相的。
The display principle and method of color metallography and its application in microstructure analysis were introduced,the microstructure color,morphology and quantitative calculation results of the color and the black and white metallography of the dual-phase steel and the tire cord steel were compared.The results show that the microstructure of the dual-phase steel and the tire cord steel can be clearly identified because of the color metallography has bright colors and strong contrast.The ferrite of the dual-phase steel is pale yellow,the martensite and the retained austenite are bright white,and the bainite is dark brown.The pearlite of the tire cord steel is bright white,and the sorbite is blue,black,brown,gray,and so on.The area fraction of each phase in the microstructure can be calculated,and the quantitative analysis can be realized.The quantitative analysis precision of color metallography is much higher than that of the traditional black and white metallography.
