In this paper the effect of isothermal forging process parameters on the microstructure and
the mechanical properties of TA15 titanium alloy was researched. The results of the tests indicate
that, in the range of temperature of 850 °C~980 °C and deformation degree of 20%~60%, with the
increase of temperature or deformation, as the reinforcement of deformation recrystallization, the
primary α-phase tends to the spherical shape and secondary α-phase transforms from the acicular
shape to fine and spherical shape with disperse distribution, which enhance the tensile properties at
room and high temperature. With the increment of forging times, the spheroidization of primary
α-phase aggrandizes and secondary α-phase transforms from spherical and acicular shape to wide
strip shape, which decrease the tensile properties at room and high temperature. The preferable
isothermal forging process parameters are temperature of 980 °C, deformation degree of 60%, and
few forging times.
The present study focuses on the effect of 1% Zr addition on the microstructure, tensile properties and superplasticity of a forged SP700 alloy. The results demonstrated that Zr has a significant effect on inhibiting the microstructural segregation and increasing the volume fraction of β-phase in the forged SP700 alloy. After annealing at 820 °C for 1 h and aging at 500 °C for 6 h, the SP700 alloy with 1% Zr showed a completely globular and fine microstructure. The yield strength, ultimate tensile strength and tensile elongation of the alloy with optimized microstructure were 1185 MPa, 1296 MPa and 10%, respectively. The superplastic deformation was performed at 750 °C with an elongation of 1248%. The improvement of tensile properties and superplasticity of the forged SP700 alloy by Zr addition was mainly attributed to the uniform and fine globular microstructures.
