The unusual character of microstructure evolution during "abc" deformation of commercial-purity titanium [PDF]

, 2022
Microstructure evolution during "abc" deformation of commercial-purity titanium was investigated. Continuous dynamic recrystallization (CDRX) played a dominant role in the microstructural changes, although mechanical twinning also contributed to some ...

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.

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

Decreasing the mechanical anisotropy of the forged Mg-8.5Gd-2.5Y-1.5Zn-0.5Zr alloy by modulating blocky LPSO particles using multi-directional forging

Journal of Magnesium and Alloys
The blocky LPSO particles were modulated by single-directional and multi-directional forging, and the effect of blocky LPSO particles on the anisotropy of mechanical properties of Mg-8.5Gd-2.5Y-1.5Zn-0.5Zr alloy forged parts was investigated.
