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 ...

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 ...

Design of Eutectic High Entropy Alloys [PDF]
Metallurgical and Materials Transactions A (2022), 2021 Eutectic high entropy alloys (EHEAs) are emerging as an exciting new class of structural alloys as they have shown very promising mechanical properties. However, how to design these alloys has been a challenge. In this work, a simple approach is presented for designing EHEAs.
