Study on the plasticity improvement mechanism and grain refinement of AZ80 Mg alloy under cryogenic multi-directional forging

Journal of Materials Research and Technology
The introduction of twin lamellae and dislocation interaction through Multi-directional forging (MDF) at room temperature (RT) has been reported to significantly improve the mechanical properties of Mg alloys.

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 ...

Microstructure Evolution of AZ80 Magnesium Alloy during Multi-Directional Forging Process

MATERIALS TRANSACTIONS, 2014
Grain refinement of a magnesium alloy, AZ80, was studied in multi-directional forging (MDF) with decreasing temperatures from 683 to 573K. The MDF was carried out up to accumulative true strains of around 7 with changing the loading direction from pass to pass.

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.

“Mongolians can find their feet anywhere, except in Mongolia”: Mongolian aspirations and the moral value of migrant labour in Korea

The Australian Journal of Anthropology, EarlyView.
Abstract This article draws on the narratives of Mongolians who have worked in Korea to explore the experience of migrant labour and the role work abroad plays in Mongolian identities and life projects. Four different categories of worker are discussed: those working on 3 month visas; those working illegally having overstayed their visa; contract ...

‘We Do Not Forget, We Do Not Forgive’: Anti‐Feminicide Collages and the Commemorative Politics of Care in Urban Space

Tijdschrift voor Economische en Sociale Geografie, EarlyView.
Abstract This paper explores the commemorative practices of two feminist collectives engaging in anti‐feminicide collages in the cities of Paris and Montreuil. Based on ethnographic fieldwork conducted between 2023 and 2025, it examines how these activist interventions, as temporary urban memorials, intersect memory‐work and care‐work in urban space ...

Effects of multi-directional forging process on coarse crystalline phases and mechanical properties of 2195 Al–Cu–Li alloy

Journal of Materials Research and Technology
The 2195 Al–Cu–Li alloy, extensively used in aerospace applications such as rocket tank transition rings, suffers from coarse crystalline phases formed during casting.

Strengthening mechanism based on dislocation-twin interaction under room temperature multi-directional forging of AZ80 Mg alloy

Journal of Materials Research and Technology
Twin and dislocation have critical influence on the mechanical properties of the widely used AZ80 magnesium alloy. In the present work, we designed room temperature multi-direction forging (MDF) at different strain amplitudes (3% and 6%) with a same ...
