Direct Evidence for Dynamic Phase Transformation during High Temperature Deformation in Ti-64 [PDF]

MATEC Web of Conferences, 2020
The microstructure of Ti-64 strongly affects the forming and in-service behaviour of aerospace components. The development of microstructure, including crystallographic texture, during thermomechanical processing involves changes caused by deformation ...

Cryogenic Deformation Behavior and Microstructural Characteristics of 2195 Alloy

Metals, 2021
Cryogenic deformation can improve the strength and plasticity of Al–Li alloy, although the underlying mechanism is still not yet well understood. The effects of cryogenic temperature on the tensile properties and microstructure of an Al–Cu–Li alloy were ...

Hot Deformation Characteristics and Processing Parameter Optimization of Al–6.32Zn–2.10Mg Alloy Using Constitutive Equation and Processing Map

Metals, 2021
Hot compression tests over the temperature range from 350 °C to 500 °C and strain rates range from 0.001 s−1 to 1 s−1 for homogenized Al–6.32Zn–2.10Mg alloy were carried out on a Gleeble-3800 thermal simulation machine to characterize its hot deformation

Gradient cell–structured high-entropy alloy with exceptional strength and ductility

Science, 2021
Description Strength by cyclic torsion For most alloys, conventional or high entropy, increasing strength comes at the cost of poor ductility. Although there are many strategies to break this inverse relationship, Pan et al.

Constitutive model and hot workability of 2195 Al-Li alloy based on stress correction

Journal of Aeronautical Materials, 2021
The isothermal compression tests of 2195 Al-Li alloy annealed at 400 - 490 ℃ and strain rate 0.01-10s−1 were carried out. The true stress-strain curve obtained from the experiment was modified by friction force and temperature rise effects, and the ...
