An Experimental Study on Evolution of Grain‐Scale Stress/Strain and Geometrical Necessary Dislocations in Advanced TA15 Titanium Alloy during Uniaxial Tension Deformation

“…[1] TA15 alloy, with a nominal composition of Ti-6Al-2Zr-1Mo-1V, consists of a dominant a phase (hexagonal close-packed, hcp) and a fewb phase (body-centered cubic, bcc). [1][2][3] However, because of low symmetry of HCP crystal structure and the special lamellar grain morphology, plastic deformation of near-a titanium is relatively heterogeneous at mesoscale. The typical microstructures of TA15 which is subjected to b forging or cooled down form b phase region are composed of a lamellae and thin b layers.…”

“…The typical microstructures of TA15 which is subjected to b forging or cooled down form b phase region are composed of a lamellae and thin b layers. [2] As a typical near-a titanium alloy, TA15 alloy is widely used in fan and compressor regions of jet engines because of its high specific strength, excellent thermal stability, low growth rate of fatigue crack, and strong corrosion resistance. [1][2][3] However, because of low symmetry of HCP crystal structure and the special lamellar grain morphology, plastic deformation of near-a titanium is relatively heterogeneous at mesoscale.…”

[1][2][3] However, because of low symmetry of HCP crystal structure and the special lamellar grain morphology, plastic deformation of near-a titanium is relatively heterogeneous at mesoscale. In addition, these characteristics reduce tensile ductility and result in low fatigue life and high spring back compared with a þ b and b titanium alloys.…”

Nickel(II) Tetraphenylporphyrin as an Efficient Photocatalyst Featuring Visible Light Promoted Dual Redox Activities

“…Standard synthesis of the purple colored NiTPP was developed by Adler [14] and the physicochemical properties were examined. [15] However, the catalytic efficiency of such readily accessible, cheap and bench stable complex in organic synthesis has never been explored. The catalyst exhibits an absorption maxima at 417 nm followed by a small hump at 445 nm ( Figure 1).…”

Constitutive Model and Processing Maps for a Ti‐55511 Alloy in β Region

“…Once the accumulated dislocation density exceeds a critical value, DRX will occur. The nucleation and growth of DRX grains cause the annihilation of dislocation, which decreases the WH rate and the flow stresses . However, because of the high stacking fault energy of β phases, the DRV is strong enough to balance the WH, and it is hard for the dislocation density to exceed the critical values.…”
