High-temperature compression testing and microstructural characterization of near-α titanium alloy TC30 for flow-forming applications

Hot Deformation Behavior and Microstructure Evolution of a Novel Near-α Titanium Alloy with Initial Lamellar Microstructure During Hot Compression

The hot deformation behavior and microstructure evolution of a novel near-α Ti65 titanium alloy with an initial lamellar microstructure were investigated by isothermal compression. Compression tests were conducted at 950–1010 °C in the α + β phase region and 1050–1110 °C in the β phase region, with strain rates of 0.01...

Hot Deformation Behavior and Microstructural Evolution of a High-Strength Mg-Gd-Y-Zr Alloy

Mg-Gd-Y-Zr alloys, with strong age-hardening and thermal stability, are ideal for lightweight load-bearing components, yet forming large complex parts is limited by high sensitivity to hot deformation parameters. This work investigates the hot deformation behavior and microstructure evolution of a Mg-9Gd-4Y-0.5Zr (wt.%...

Effect of Initial Grain Size on High‐Temperature Tensile Deformation and Microstructural Evolution of GH2907 Alloy

To investigate the effect of grain size on the tensile deformation behavior and dynamic softening mechanisms of GH2907 alloy at 500 and 600 °C, fine‐grained (FG) and coarse‐grained (CG) specimens were prepared via solution treatment. High‐temperature tensile tests were performed at 500 and 600 °C, combined with mechani...

Hetero-deformation induced stress and its microstructural morphology dependence in a near-alpha titanium alloy

Hetero-deformation induced (HDI) stress and the effect of microstructural morphology on it were investigated in a near-alpha titanium alloy featuring lamellar and equiaxed initial microstructures. The development of HDI stresses were confirmed in the two types of microstructures under tensile tests. While both microstr...

Effect of Temperature and Strain Rate on the Thermomechanical Response and Dynamic Restoration Mechanisms of Ti-6Al-4V Alloy During Forging

The thermomechanical behavior of the Ti-6Al-4V (Ti64) alloy under hot deformation is determined by a complex interplay between strain hardening and thermally assisted restoration processes that finally lead to the formation of the resultant microstructure and mechanical properties. In this research, the effects of defo...
