采用金相组织分析、拉伸和夏比冲击试验等方法，研究了Zr-Ti复合脱氧对低合金高强度钢组织和力学性能的影响。实验结果表明，锆钛基脱氧剂的加入，形成了细小的锆钛复合氧化物。与铝基脱氧剂脱氧的钢相比，Zr-Ti脱氧的钢中含有大量细小均匀分布的氧化物，组织均匀，强度提高。用Zr-Ti脱氧的厚钢板的塑性和韧性也有很大的提高，这显然是由于MnS的球化和均匀分散。(C)© 2016 Elsevier B. V.版权所有。
Effect of Zr-Ti combined deoxidation on the microstructures and mechanical properties of high-strength low-alloy steels were investigated by means of microstructure analysis, tensile- and Charpy impact-tests. Experimental results showed the addition of Zr-Ti based deoxidizing agent resulted in the formation of fine Zr-Ti complex oxides. Owing to abundant finely oxides dispersed in the matrix uniformly, the microstructures deoxidized using Zr-Ti was uniform and the strength was enhanced comparing against the steels deoxidized using Al based deoxidizer. The ductility and toughness of the thick steel plates deoxidized using Zr-Ti were also considerably improved, apparently due to the spheroidization and uniform dispersion of MnS.
