摘要

本文描述了一种成功实现的用于激光粉末床熔融（LPBF）打印骨科植入物的Ti-Zr-Nb形状记忆合金的化学成分控制方法。结果表明，为了使印品中Ti- 18zr - 15nb （at.%）的含量达到目标，必须调整铸锭成分，使Ti含量提高2.5 %，Zr和Nb含量分别降低1 %和1.5 %。这些修改补偿了粉末雾化和LPBF加工过程中发生的成分变化，并且 - 在550℃下熔融后退火30 min - 后，打印出具有优异室温超弹性的产品：超弹性恢复应变为2.6 %，总恢复应变为6.1 %。所获得的材料力学性能（极限抗拉强度为725 MPa，杨氏模量为53GPa）使本研究的lpbf打印和退火Ti-18Zr-15Nb合金成为骨科植入物的有希望的候选材料。

Improving superelasticity of a laser powder bed-fused Ti-Zr-Nb alloy via the ingot composition adjustments

This paper describes a successfully implemented method for controlling the chemical composition of Ti-Zr-Nb shape memory alloys for laser powder bed fusion (LPBF) printing of orthopedic implants. It is shown that to achieve the target Ti-18Zr-15Nb (at.%) composition in the printed product, the ingot composition must be adjusted by increasing the Ti content by 2.5 % while decreasing the Zr and Nb contents by 1 % and 1.5 %, respectively. These modifications compensate for compositional variations occurring during powder atomization and LPBF processing, and − following a post-fusion annealing at 550℃ for 30 min − result in a printed product with excellent room-temperature superelasticity: a superelastic recovery strain of 2.6 % and a total recovery strain of 6.1 %. The obtained mechanical properties of the material (an ultimate tensile strength of 725 MPa and Young’s modulus of 53GPa) make the LPBF-printed and annealed Ti-18Zr-15Nb alloy of this study a promising candidate for orthopedic implants.
