Abstract

In the present study, (Ti, Nb)B reinforced Ti-Nb-Zr-Mn alloys were successfully fabricated through ball milling and spark plasma sintering (SPS) process with the addition of TiB₂. The microstructure, mechanical behavior, and corrosion resistance in simulated body fluid of the as-prepared alloys were systematically investigated. It was found that (Ti, Nb)B phases were in situ formed through reaction between the Ti-Nb-Zr-Mn matrix and TiB₂ particles, which significantly enhanced the mechanical strength of the alloys. As the TiB₂ with equivalent B mass fractions increased from 0 to 1 wt.%, the ultimate tensile strength of the alloys improved significantly from 945 ± 13 MPa to 1259 ± 8 MPa, while the elongation reduced sharply from 20.2 ± 2.2% to 1.9 ± 0.5%. Microhardness tests showed that the materials’ hardness increased as the fraction of the (Ti, Nb)B phase increased. Notably, the elastic modulus increased from 77.1 ± 0.5 GPa to 93.7 ± 0.7 GPa. Moreover, the appropriate introduction of B was beneficial to the corrosion resistance of the alloy in simulated body fluids.

添加B对Ti-24Nb-4Zr-2Mn合金组织、力学性能和腐蚀行为的影响

在本研究中，通过球磨和火花等离子烧结（SPS）法制备了（Ti, Nb）B增强Ti-Nb- zr - mn合金。系统地研究了合金的显微组织、力学行为和在模拟体液中的耐蚀性。结果表明，Ti-Nb- zr - mn基体与TiB2颗粒发生原位反应形成（Ti, Nb）B相，显著提高了合金的机械强度。当含等效B质量分数的TiB2从0 wt.%增加到1 wt.%时，合金的抗拉强度从945±13 MPa显著提高到1259±8 MPa，伸长率从20.2±2.2%急剧下降到1.9±0.5%。显微硬度测试表明，随着（Ti, Nb）B相含量的增加，材料的硬度也随之增加。弹性模量从77.1±0.5 GPa增加到93.7±0.7 GPa。此外，适当引入B有利于合金在模拟体液中的耐腐蚀性。
