摘要:

在35MnB履带钢中添加Ti并使用XRD、SEM、EBSD、TEM、Aspex等手段对其表征，研究了Ti对这种钢中的第二相粒子和性能的影响。结果表明，添加Ti能显著变质钢中的夹杂物和细化晶粒，使其力学性能提高。添加Ti的实验钢冲击韧性比未添加Ti的钢提高了50%以上；添加0.045% (质量分数) Ti能调控钢中的第二相颗粒，使强韧性协同提高。添加Ti使35MnB钢强化的机制是：Ti与钢中的C、N发生反应生成第二相粒子，这种第二相粒子能钉扎晶界和位错使钢中的奥氏体晶粒的高温粗化受到抑制，从而细化晶粒、增强晶界稳定性和提高位错密度，使钢的强韧性提高。

Abstract：

35MnB steel, a low-alloy high-strength steel, is used for making track shoes, yet its properties fail to meet the requirements of new-generation track steels due to detrimental inclusions (BN, MnS, etc.) formed during smelting and solidification processes. To mitigate the detrimental effect of inclusions, herein, the influence of Ti microalloying on the formation and distribution of secondary phase particles and mechanical properties of 35MnB steel was systematically investigated by means of techniques such as XRD, SEM, EBSD, and TEM, as well as Aspex inclusion analysis system and universal testing machine, etc. The results demonstrate that Ti addition effectively optimizes inclusion distribution, remarkably refines grains, and enhances the mechanical properties of the alloy steel. Notably, with the addition of 0.045% (mass fraction) Ti, the Ti-micro-alloyed steel exhibits > 50% improvement in impact toughness compared to that of the Ti-free steel, therewith, an optimal regulation of secondary phase particles may be acquired for simultaneous enhancement in strength-toughness. The strengthening mechanisms may involve Ti reacting with C and N to form secondary phase particles that pin grain boundaries and dislocations, while inhibiting the high-temperature coarsening of austenite grains, thereby refining grains, stabilizing grain boundaries, increasing dislocation density, and ultimately improving the performance of the 35MnB steel.
