摘　　要：对Fe-C-B合金的凝固过程与凝固组织特征进行分析。结合相图研究结果,讨论了合金中硬质相种类与形成机理,初步总结了成分对Fe-C-B合金的组织与性能的影响。指出促进和推动Fe-C-B合金的研究与应用,需要在进一步完善Fe-C-B三元相图基础上,深入研究凝固条件、成分对无铬Fe-C-B合金组织与性能的影响,探寻进一步改善其组织与性能的途径。The solidification process and characteristic of solidification microstructure of Fe-C-B alloy were analysed.Combining the research results of phase diagram,the types and formation mechanism of hard phases in the alloy were discussed,and the effect of composition on the microstructure and properties of Fe-C-B alloy was introduced primarily.A direction to promote the research and application of Fe-C-B alloy was pointed out,which that based on further improving phase diagram of Fe-C-B ternary system,to launch in-depth study on the effect of solidification condition and composition on the microstructure and properties of Fe-C-B alloy without chromium addition,and explore the way to further improve on the microstructure and properties of Fe-C-B alloy.
