Abstract Zr-Ti binary alloys are prepared using a nonconsumable tungsten electrode under Ti-gettered inert atmosphere (argon). Microstructures are observed mainly as α phase using x-ray diffraction. A tensile test is performed to investigate the tensile strength of a series of Zr-Ti binary alloys at room temperature. The findings indicate that increasing Ti concentration results in an initial increase (<50at% of Ti) and then a decrease in tensile strength. The Zr55Ti45 (at%) component exhibits the maximum tensile strength of 1216.68 MPa, which is much higher than that of pure Ti (increased by approximately 200%) or pure Zr (increased by approximately 100%). The potential mechanisms for the remarkable tensile strength are solid solution strengthening and grain refinement.
