Effect of Competitive Precipitation and Texture Weakening on Mechanical Properties in a Mg-Gd-Y-Nd-Zr Alloy Processed by Integrated Multi-Directional Forging and Extrusion

Metals
As the lightest metallic structural material, magnesium alloys face a fundamental trade-off between strength and ductility, limiting their broader application.

Uncovering hidden bias in neutron diffraction residual strain measurements

Journal of Applied Crystallography, EarlyView.
This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

Superplasticity of Fine-Grained Magnesium Alloy AZ31 Processed by Multi-Directional Forging

MATERIALS TRANSACTIONS, 2007
Superplasticity was studied in a fine-grained magnesium alloy AZ31 processed by multidirectional forging (MDF) under decreasing temperature conditions. Tensile tests were carried out at temperatures from 393 K to 473 K and at various strain rates. Superplasticity appears even at a low temperature of 393 K with a stress exponent of around 5.6 and a ...

Microstructure, texture, mechanical properties, and corrosion behavior of biodegradable Zn-0.2Mg alloy processed by multi-directional forging [PDF]

This study systematically investigated the microstructure, mechanical properties, and corrosion behavior of an extruded Zn-0.2Mg alloy processed by multi-directional forging (MDF) at 100 °C. The mean grain size was remarkably decreased from 17.2¿±¿0.5 µm

Key Practices of Knowledge Mobilization in Local Policy Settings

Public Administration Review, EarlyView.
ABSTRACT The literature on knowledge mobilization (KM) acknowledges the complex processes involved in the application of evidence to policy. However, the everyday activities employed by knowledge mobilizers to facilitate these processes have proved difficult to capture and codify.

Effect of Surface Treatment of Multi-Directionally Forged (MDF) Titanium Implant on Bone Response

Metals, 2019
Multi-directional forging (MDFing) of titanium drastically improved its mechanical properties due to the evolution of an ultrafine-grained structure. Forging strain was repeatedly applied while changing the forging axis during MDFing.

Alevi Spatial Politics: Placemaking and the Negotiation of Visibility Across Diaspora and Homeland

Studies in Ethnicity and Nationalism, EarlyView.
ABSTRACT This article examines Alevi spatial politics by analysing how space is produced, practised and negotiated across diaspora and homeland. Drawing on multi‐sited ethnographic research conducted among British Alevis in London and in Alevi villages in the Afşin–Elbistan region of Turkey, it focuses on cemevis (cem houses) as key sites of religious ...

The “Communal College:” Cross‐Ethnic Voting Rules and Census Requirements for Dyadic Consociational Democracies

Swiss Political Science Review, EarlyView.
Abstract Electoral systems in deeply divided societies are pivotal for peace and stability among ethno‐national groups. Consociationalism and centripetalism are the most widespread approaches from which derive the major incentives for electoral systems in deeply divided, dyadic societies.
