Crystallographic orientation and slip behavior of powder metallurgy Ti–6Al–4V via multi-directional forging

Journal of Materials Research and Technology
In this study, we present a microstructural and mechanical analysis of Ti–6Al–4V alloys processed by low-temperature multi-directional forging at 900 °C, achieving near-theoretical density (99.9%), with a tensile strength of 1070 MPa and elongation of 14.

The effects of die forging and age hardening on microstructure and properties of large-sized complex structural components Mg-Gd-Y-Zr alloys

Journal of Materials Research and Technology
The die forging of large-sized complex structural components Mg-Gd-Y-Zr alloy plates remains challenging due to limited slip systems and strain distribution inhomogeneity inherent to the forming process.

Grain refinement of magnesium alloys by dynamic recrystallization (DRX): A review

Journal of Materials Research and Technology, 2023
For elevated-temperature thermomechanical processing, the occurrence of recrystallization during straining is known as dynamic recrystallization (DRX), which usually happens in Mg alloys during practical hot deformation processes such as rolling, forging,

Mechanical behavior and microstructures of aluminum processed by low strain amplitude multi-directional confined forging

Journal of Materials Research and Technology, 2020
Severe Plastic Deformation (SPD) leads to grain refinement and strengthening of metals. Among the many SPD processing methods, Multi-Directional Forging (MDF) is the only one where in-situ material stress–strain curves can be obtained. These are adequate

Brokers, Collaborators and Knowledge Translators: Expanding the Role of Research Assistants in Geographic Research

Asia Pacific Viewpoint, EarlyView.
ABSTRACT While ‘local’ research assistants (RA) often play a key role in knowledge production in fieldwork‐based disciplines like geography, their role and agency often remain silenced. This paper brings together scholarship in feminist geography and critical development studies to reposition RAs as brokers, collaborators, and knowledge translators.

The Geoeconomic Turn on Stage: National Identity and the Interpretation of the EU's Trade Sustainability Diplomacy in Indonesia and Vietnam

JCMS: Journal of Common Market Studies, EarlyView.
Abstract In the context of the European Union's (EU's) geoeconomic shift, the governance of Trade and Sustainable Development (TSD) has become a central yet contested pillar of its external trade policy. Accusations of green colonialism highlight the stakes around how partner countries interpret the EU's normative agenda.
