Low-temperature superplasticity of titanium alloy Ti-6Al-4V

Results of tests at temperatures of 650-800 C and at strain rates of 1∙10-4 - 2∙10-1 s-1 for uniaxial tensile specimens of titanium alloy Ti-6Al-4V, cut along and across the rolling direction sheet is given. Revealed low-temperature superplasticity studied sheets of titanium alloy Ti-6Al-4V. Noted that the maximum plastic sheets shown at 750 and 800 C. In the permissible limits of experimental scatter plates are isotropic in the longitudinal and transverse directions relative to the flow stress and ductility in the temperature-speed range.
