Abstract
A new generation of beta Ti-Nb-Zr and Ti-Nb alloys with considerable deformation capacity during compression tests, high ductility, and great mechanical strength with the closest elastic modulus of the bone has been studied to replace the commercial Ti-6Al-4V alloy. In this investigation, the compressive mechanical properties and microstructure of Ti-47Nb and Ti-30Nb-8Zr alloys were analyzed and compared with those of the cpTi grade 4. The Ti-30Nb-8Zr alloy has higher compressive strength than Ti-47Nb and cpTi grade 4. The Ti-30Nb-8Zr alloys presented β matrix with equiaxed grains without precipitates and with α-martensitic phase with precipitates. The Ti-47Nb alloy presents highest ductility.
