Extended post-uniform elongation during warm tensile deformation of Ti–6Al–4V: roles of deformation-assisted martensite reversion and lamellar β continuity/refinement

Journal of Materials Research and Technology
Two α′-containing microstructures, a fully martensitic (α′) structure and a dual-phase α+α′ structure (≈45–50 % α′), were generated in Ti–6Al–4V by solution-treatment above and below the β-transus, followed by water quenching.

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Nuclear reactions in hot stellar matter and nuclear surface deformation

, 2006
Cross-sections for capture reactions of charged particles in hot stellar matter turn out be increased by the quadrupole surface oscillations, if the corresponding phonon energies are of the order of the star temperature.

Microstructural Evolution and Mechanical Performance of Plasma‐Assisted Hybrid Friction Stir Welded Dissimilar Aluminum–Copper Joints

Advanced Engineering Materials, EarlyView.
Plasma‐assisted hybrid friction stir welding of dissimilar AlCu joints employs localized plasma preheating to balance heat input and enhance plastic flow. The optimized process reduces axial force by up to 35%, refines the microstructure, and achieves ≈96% joint efficiency.
