“…void nucleation, growth and coalescence. Upon deformation, microvoids have been reported to nucleate and grow from: second-phase particles through matrix particle decohesion and particle cracking (Puttick, 1959); triple junctions between grains of identical phases (Tan et al, 2007); interfaces between different phases (Greenfield and Margolin, 1972); slipband intersections (Gysler et al, 1974); dislocation cell boundaries (Gardner et al, 1977); etc. The anisotropic nature of these mechanisms is clearly shown (Benzerga et al, 2004).…”

“…Therefore, it is important to improve the initial microstructure (such as grain refinement and THP) and optimize the processing conditions which can enhance the superplasticity and reduce the time and temperature of diffusion bonding [145][146][147][148][149][150][151]. Mathematical modeling and numerical simulation can guide the design and optimization of the process and have drawn extensive applications in superplastic forming [152][153][154][155]. However, the mathematical model for diffusion bonding still needs further investigations.…”

Titanium alloys have been used extensively in industry fields including aviation, aerospace and automobile due to their excellent comprehensive properties. Research and development of advanced plastic forming technology are of great importance to manufacturing titanium products of high performance and lightweight with low cost and short cycle. This paper analyzes the development tendencies of titanium alloy forming technology. Recent achievements in precision forming, microstructure control and multi-scale simulation of titanium alloys are reviewed. The forming techniques of large-sale integral complex components are presented. titanium alloys, precision forming, microstructure control, multi-scale simulation, large-scale integral complex components Citation:Yang H, Fan X G, Sun Z C, et al.

“…Similar results were also reported on the tensile deformation of CP Ti at different temperatures. 3,4) Tan et al 5) found that many cavitations formed at grain boundaries (GBs) of triple points during tensile tests of a CP Ti alloy at relatively low temperatures (below 873 K (600°C)), but such a phenomenon was not observed at higher temperatures (e.g., 1023 K (750°C) and 1073 K (800°C)), because most defects can be sintered when deformed at temperatures above 1023 K (750°C). Chichili et al 6) and Nemat-nasser et al 7) reported that the deformation twinning is a very important deformation mode during the tensile deformation of pure Ti at different temperatures, and that the density of twins increases markedly with increasing strain rate and decreasing temperature.…”

Characterizations of Temperature-Dependent Tensile Deformation and Fracture Features of Commercially Pure Titanium

Tensile deformation and fracture behavior of a commercially pure (CP) titanium were investigated at different temperatures through mechanical tests, microstructural observations and fractal analyses. It was found that, with increasing temperature, the number and size of microvoids formed along shear bands (SBs) or at the intersections of SBs on the deformed specimen surface increase, and the fractal dimensions of the scanning profile at the surface near fracture increase correspondingly, and the ones measured perpendicular to the tensile direction is obviously larger than those parallel to the tensile direction, indicating an increased concentration of plastic deformation of CP Ti along the tensile axis. The diameter and depth of dimples on the fracture surfaces of CP Ti increase significantly with increasing temperature, giving rise to a higher fracture surface roughness reflected by a higher fractal dimension. TEM observations demonstrated that the plastic deformation of CP Ti is gradually occupied by dislocation slipping rather than twinning with increasing temperature. This is in good agreement with the fractal analyses of the deformation and fracture features.
