The beta-titanium alloys are used for bioapplications (e.g. orthopaedic or dental implants) due to their excellent properties like biocompatibility, corrosion resistance, high strength, low Young’s modulus). The processing of these alloys is essential for their properties and therefore processing parameters should be chosen properly. In this work the effect of solution treatment temperature on properties of Ti-35Nb-Zr alloys has been studied by means of light microscopy, X-ray diffraction analysis and DSC analysis. The Ti-35Nb-2Zr alloy was prepared through powder metallurgy process (blended elemental powders, cold isostatic pressing and sintering). Sintered specimens were hot forged and solution treated at temperatures 800, 850, 900, 950 and 1000 °C for 0.5 hrs and water quenched. The grain size changed from 35 to 75 μm. In addition precipitation processes have been observed along with precipitate coarsening. The α-phase precipitation has significant influence on the matrix grain growth.
