Effect of Zn content and processing route on the microstructure, mechanical properties, and bio-degradation of Mg–Zn alloys

Journal of Materials Research and Technology, 2022
The effects of zinc content (2 and 4 wt%), heat treatment (solution-treated and T6), as well as hot deformation (extrusion and multi-directional forging (MDF)) on the microstructure, mechanical and degradation behavior of Mg–Zn alloys were studied.

A Study on the Influence of Zr on the Strengthening of the Al-10% Al₂O₃ Composite Obtained by Mechanical Alloying

Metals, 2023
Al2O3 is a traditional strengthening phase in aluminum matrix composites due to its high hardness and melting point. At the same time, zirconium is an important alloying element for heat-resistant aluminum alloys. However, its effect on the structure and

On the solution treatment of severely deformed AA2024-O and subsequent natural aging

Journal of Materials Research and Technology, 2022
In this research, the effect of applying severe strain before solid solution treatment (SST) for AA2024-O was studied. Providing concurrent insights into solutionizing behavior and microstructural evolution corresponding to hardness is important.

Numerical Investigation on the Strain Evolution of Ti-6Al-4V Alloy during Multi-directional Forging at Elevated Temperatures

High Temperature Materials and Processes, 2018
Multi-directional forging (MDF) is one of the most promising severe plastic deformation (SPD) methods used in fabricating large-scale bulk metal materials with ultra-fine grains (UFG). A finite element model for MDF is developed to investigate the strain

Synergistic enhancement of strength and toughness of β-Ti alloy with a fine grain: Effect of deformation temperature [PDF]

MATEC Web of Conferences
It is difficult for as-cast titanium alloys to achieve high strength and toughness due to the presence of coarse β grains. In this study, multi-directional forging (MDF) was employed to break down the coarse β grains into fine grains and the mechanism of

The Structural Refinement of Commercial‐Purity Copper Processed by Equal Channel Angular Pressing with Low Strain Amplitude

Advanced Engineering Materials, Volume 27, Issue 21, November 2025.
Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via
