Effect of In-situ Synthesis TiC Particle on Microstructures and Properties of Fe-based Alloy
-
摘要: 通过向Fe-Al-B合金中添加C和Ti元素的方法,在合金中原位生成了TiC颗粒,利用X射线衍射(XRD)、扫描电子显微镜(SEM)和能谱仪分析了添加TiC前后材料中相的变化、显微组织的变化及材料中各相的化学成分。结果表明,在合金中原位生成TiC颗粒后,合金组织明显得到细化,其耐熔锌腐蚀性能及强度也有大幅度提高。Abstract: The composites reinforced by TiC particle were prepared through in-situ reaction by means of adding C and Ti element to Fe-Al-B alloys. The phases transformation and the change of microstructure and chemical constitution of each phase were analyzed through X-ray diffraction (XRD) analysis, scanning electronic microscope (SEM) and energy spectrometer. The results showed that the grain of alloy was refined and the corrosion resistance of alloy to molten zinc was improved greatly after in-situ formation TiC in alloy matrix.
