The beta-titanium alloys are used mainly in bioapplicants for artifitial joints and other implants. They posses interesting properties such as, high corrosion resiatance, low Youngś modulus, good plasticity or superelasticity etc. In this work the effect of solution treatment temperature on deformation or superelasticity etc. In this work the effect of solution treatment temperature on deformation and fracture properties has been studied. The alloy Ti-35Nb-2Zr was processed via powder metalurgy proces(cold isostatic pressing, sintering and subsequent swaging). Swaged alloy was annealed at 800, 850, 900, 950 and 1000 o C . Tensile tests have been permormed on such heat treated specimens and the fracture surface has been studied in correlation with microstructure. With increasing annealing temperature both tensile strength (from 925 MPa to 990Mpa) and elongation (from 13 to 25 %) increased where the maximum values were obtained for 900 o C annealad speciments and subsequently slight decrease has been observed. The simultaneus increase of strength and elongation was attacvhed to change of deformation mechanisms which was described by studying fracture and microstructure of deformed (tensile tested) specimens.
