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

Microstructure evolution in a 316L stainless steel subjected to multidirectional forging and unidirectional bar rolling

IOP Conference Series: Materials Science and Engineering, 2014
The formation of ultrafine-grained structures was studied in a 316L stainless steel during severe plastic deformation. The steel samples were processed up to a total amount of strain of 4 at ambient temperature using two different methods, i.e., multidirectional forging and unidirectional bar rolling.

The Migration–Development Nexus Revisited: A Place‐based Mobility Perspective from the Borderlands

Development and Change, Volume 56, Issue 6, Page 1197-1227, November 2025.
ABSTRACT Migration, a fundamental characteristic of planetary life and human livelihood, has been considered a key driver of development. However, as identified by critical migration and mobility scholars, the assumed positive relationship to development has been predominantly informed by a neoliberal, managerial and sedentary view of migration ...
