Titanium and especially its alloys are highly employed materials in biomedical applications because of their balanced mechanical properties and biocompatibility. Ti-Mn alloys (1, 5, and 10 wt%. Mn) were produced by powder metallurgy as a potential alternative material for biomedical applications. Two sets of samples were produced, one set as-sintered and the other was beta (β) forged. For the as-sintered samples with a content of up to 10 wt% Mn, the tensile strength ranged from 606 to 1070 MPa. On the other hand, for the β forged alloys the tensile strength ranged from 728 to 1224 MPa and the maximum value was for Ti-5Mn. Forged Ti-5Mn exhibits a good balance of mechanical properties such as ultimate tensile strength (1224 MPa), elongation (4.6%) and Vickers hardness (415 HV). The purely elastic properties of the Ti-10Mn alloy is attributed to the effects of the omega (ω) phase, the formation of which is due to the high amount of beta stabiliser added to Ti.
钛及其合金由于其平衡的机械性能和生物相容性而被广泛应用于生物医学领域。Ti-Mn 合金（1、5 和 10wt%Mn）通过粉末冶金制成，作为生物医学应用的潜在替代材料。制备了两组样品，一组为烧结态，另一组为β锻造态。对于含 Mn 量高达 10wt%的烧结态样品，拉伸强度范围为 606-1070MPa。另一方面，对于β锻造合金，拉伸强度范围为 728-1224MPa，最大值为 Ti-5Mn。锻造 Ti-5Mn 表现出良好的力学性能平衡，如极限拉伸强度（1224MPa）、伸长率（4.6%）和维氏硬度（415HV）。Ti-10Mn 合金的纯弹性性能归因于ω（ω）相的影响，ω 相的形成是由于添加了大量的β稳定剂到 Ti 中。
