Superplastic Deformation of TC6 Alloy
The superplastic tensile tests of TC6 alloy were conducted in the temperature range of 800-900℃ by using the maximum <i>m</i> value superplasticity deformation (Max <i>m</i> SPD) method and the constant strain rate deformation method at the strain rate range of 0.0001-0.1 s&l...

description | The superplastic tensile tests of TC6 alloy were conducted in the temperature range of 800-900℃ by using the maximum <i>m</i> value superplasticity deformation (Max <i>m</i> SPD) method and the constant strain rate deformation method at the strain rate range of 0.0001-0.1 s<sup>-1</sup>. The stress-strain curve of the tensile tests was obtained and the microstructure near the fracture were analyzed by metallographic microscope. The result shows that the superplasticity of TC6 alloy is excellent, and the elongation increases first and then decreases with the increase of strain rate or temperature. When the temperature is 850℃ and strain rate is 0.001 s<sup>-1</sup> at constant stain rate tensile tests, the elongation reaches up to 993%. However, the elongation using Max <i>m</i> SPD method at 850℃ is 1353%. It is shown that the material can achieve better superplasticity by using Max <i>m</i> SPD tensile compared to constant stain rate tensile under the same temperature. The superplastic deformation of TC6 alloy can enhance the dynamic recrystallization behavior significantly, the dynamic recrystallization behavior is promoted when strain rate and temperature are increased. |
