Effects of Mn Content on Microstructure and Properties of Biomedical Ti-29Nb-6Ta-5Zr Alloy
摘 要
采用非自耗真空电弧炉熔炼了Ti-29Nb-6Ta-5Zr-xMn(x=0,1,2,4,质量分数/%)合金,并进行了固溶处理,研究了锰含量对该合金显微组织、力学性能及电化学腐蚀性能的影响。结果表明:试验合金的组织均为单一β等轴晶,其平均晶粒尺寸和晶格常数均随锰含量的增加而减小;试验合金的抗拉强度、屈服强度和硬度均随锰含量的增加而增大,当锰质量分数为4%时,抗拉强度、屈服强度和硬度均最大,分别为609 MPa,585 MPa,252 HV,比未添加锰的分别提高了75.2%,70.1%,58.4%;伸长率和弹性模量随锰含量的增加先减小后略有增大,但增大幅度并不大;添加质量分数为4%锰的试验合金的自腐蚀电位最高,腐蚀倾向最小。
Abstract
Ti-29Nb-6Ta-5Zr-xMn(x=0,1,2,4,mass fraction/%) alloys were fabricated by nonconsumable electrode vacuum arc furnace and treated by solid solution. The effects of Mn content on the microstructure, mechanical properties and electrochemical corrosion resistance of the alloy were studied. The results show that the microstructures of all tested alloys were composed of a single β phase with equiaxed grains. The average grain size and lattice constant decreased with increasing content of Mn. The tensile strength, yield strength and hardness of the tested steel increased with increasing content of Mn and reached the largest values of 609 MPa, 585 MPa and 252 HV with 4wt% Mn, improved by 75.2%,70.1% and 58.4% comparing to those without Mn, respectively. The elongation and elastic modulus first decreased and then increased slightly with increasing content of Mn, however, the increase range was small. The corrosion potential of tested alloy containing 4wt% Mn was the highest, indicating the minimal tendency of corrosion.
