Abstract: We consider the creep of a hydrogenated rod made of VT6 (Ti-6Al-4V) titanium alloy with a piecewise constant dependence of the stress on time up to failure. The results of an experimental and theoretical study on the effect of the concentration of previously introduced hydrogen on the creep and long-term strength of tensile rods made of VT6 titanium alloy at a temperature of 600$^\circ$C and constant nominal tensile stresses in the range from 47 to 217 MPa.
Keywords: creep, long-term strength, hydrogen saturation, step loading.
