Dynamic reverse phase transformation induced high-strain-rate superplasticity in low carbon low alloy steels with commercial potential

Scientific Reports, 2017
Superplastic materials are capable of exhibiting large tensile elongation at elevated temperature, which is of great industrial significance because it forms the basis of a fabrication method to produce complex shapes.

The Effect of Severe Plastic Deformation on Mechanical Properties for A6061 Aluminum Alloy Fabricated by Multitypes of Bending Forming

Material Design &Processing Communication, Volume 2026, Issue 1, 2026.
Severe plastic deformation (SPD) is a well‐known processing technique used to impose large plastic strains and modify the mechanical properties of metal‐based materials. In this work, SPD was introduced into A6061 aluminum alloy sheets via two forming processes: differential diameter rolling (DDR) and V‐bending.

Development and Evaluation of a Novel Self‐Centering Tristable Meta‐Structural Damper

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
To enhance the seismic resilience of structures, this study proposes a novel self‐centering tristable meta‐structural damper design. The superelastic bistable elements (BEs) are developed and integrated within a meta‐structural framework, which enables the damper to realize state transitions and self‐centering capabilities.

Achieving Complex Nanostructures: The Role of Hydrogen in Controlling Mechanical Alloying and Microstructure Evolution in the TiVZrNbHf‐Cu System

Advanced Science, Volume 12, Issue 33, September 4, 2025.
This study highlights the drastic influence hydrogen has on the microstructure evolution during severe plastic deformation. High‐pressure torsion of a TiVZrNbHf‐Cu composite results in mechanical alloying and subsequent amorphization, whereas replacing the high entropy alloy with the corresponding hydride stabilizes a two‐phase microstructure.
