Cryogenic ductility enhancement mechanisms of AA7075 alloy under different deformation conditions: Tensile tests and incremental sheet forming

Materials & Design
High-strength aluminum alloys are potential structural materials for aerospace and transportation fields. However, the poor formability at room temperature (RT) and the unstable microstructure at elevated temperature limit the wider application in which ...

Shear relaxation behind the shock front in $\langle$110$\rangle$ Molybdenum - From the Atomic Scale to Continuous Dislocation Fields

, 2018
In this work we study shock-induced plasticity in Mo single crystals, impacted along the crystal orientation. In particular, the shear relaxation behind the shock front is quantitatively inspected.

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration

Advanced Functional Materials, EarlyView.
Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

High-cycle fatigue behavior of TWIP steel with graded grains: breaking the rule of mixture

Materials Research Letters, 2019
We report a method, named as T & A treatment, to improve the high-cycle fatigue (HCF) property of twinning-induced plasticity (TWIP) steel without sacrificing its ductility and work-hardening ability.

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

Advanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...

Electro‐Chemo‐Mechanical Coupling in Hf0.5Zr0.5O2 Ferroionic Heterostructures

Advanced Functional Materials, EarlyView.
Schematic of a ferroionic HZO heterostructure where epitaxial interfaces enable dynamic oxygen‐vacancy exchange, coupling ionic and ferroelectric degrees of freedom. Vacancy‐mediated polarization modulation biases HZO polymorphism, suppresses leakage, and enhances piezoelectric response, yielding distinct butterfly‐loop evolution and diode‐like ...
