“…The Arrhenius hyperbolic sinusoidal model, [19] whose expression is shown in Equation , is used for the establishment of the constitutive equation of the Ti‐2.5Zr‐2Al‐1(Si,C) titanium alloy. Considering the effect of strain on the material constants A , α , n, and activation energy Q , the strain compensation constitutive equation is established to reduce the error of the constitutive equation [20,21] . The fitting process of the constitutive equation is summarized in Supporting Information : Appendix B, and the parameters of the constitutive equation under different strains are shown in Table 1.…”

An in situ autogenous particle‐reinforced Ti‐2.5Zr‐2Al‐1(Si,C) titanium alloy is prepared by vacuum induction melting. The wide range of an effective strain between 0.2 and 1.2 and the corresponding microstructure are obtained by the double‐cone high‐throughput compression test and finite element simulation. The deformation mechanism diagram with strains of 0.2–1.2 and strain rates of 0.7–1.5 s−1 at 900°C is constructed. When the strain rate is 1.3 s−1, dynamic recovery occurs in the small strain range (<0.377), dynamic recrystallization (DRX) occurs in the medium strain range (0.377–1.182), and deformation instability occurs in the large strain range (>1.182), resulting in the deformation bands. High‐angle annular dark field and high‐resolution transmission electron microscopy are used to determine the existence of bimodal particle distribution, namely micron‐scale TiC particles and nano‐scale Ti5Si3 and (Zr, Si) particles. The average radius of the (Zr, Si) nanoparticles measured by small angle neutron scattering is 19.3 nm, and the volume fraction is 0.35%. DRX grains with an average size of 0.49 μm are obtained at 900°C, strain rate of 1.3 s−1, and strain of about 0.6. Micron‐scale particles stimulated DRX nucleation, while nanoscale particles hindered the growth of new grains, resulting in grain refinement.

Deformation instability is a macroscopic and microscopic phenomenon of non-uniformity and unstable deformation of materials under stress loading conditions, and it is affected by the intrinsic characteristics of materials, the structural geometry of materials, stress state and environmental conditions. Whether deformation instability is positive and constructive or negative and destructive, it objectively affects daily life at all times and the deformation instability based on metal-bearing analysis in engineering design has always been the focus of attention. Currently, the literature on deformation instability in review papers mainly focuses on the theoretical analysis of deformation instability (instability criteria). However, there are a limited number of papers that comprehensively classify and review the subject from the perspectives of material characteristic response, geometric structure response, analysis method and engineering application. Therefore, this paper aims to provide a comprehensive review of the existing literature on metal deformation instability, covering its fundamental principles, analytical methods, and engineering practices. The phenomenon and definition of deformation instability, the principle and viewpoint of deformation instability, the theoretical analysis, experimental research and simulation calculation of deformation instability, and the engineering application and prospect of deformation instability are described. This will provide a reference for metal bearing analysis and deformation instability design according to material deformation instability, structural deformation instability and localization conditions of deformation instability, etc. From the perspective of practical engineering applications, regarding the key problems in researching deformation instability, using reverse thinking to deduce and analyze the characteristics of deformation instability is the main trend of future research.

Titanium alloy tubes were an ideal material to replace steel tubes. However, the relationship between piercing temperature and dimensional accuracy for titanium alloy seamless tubes was unclear. Therefore, the effects of piercing temperature on the stress—strain distribution and dimensional accuracy of Ti80 titanium alloy were studied using thermal simulation compression tests, finite element numerical analysis optimization and optical microscopy. Pierced at 1050 °C, Ti80 titanium alloy was cross-rolled and perforated to obtain a capillary tube, whose dimensional accuracy was better than that of those pierced at 850 °C and 950 °C. The microstructure of Ti80 seamless tubes was layered α-Ti, grain boundary β-Ti and a Widmannstatten structure. The tensile strength, yield strength and absorbed energy were 867 MPa, 692 MPa and 52 J, respectively.
