Effects of SiCp distribution on microstructure, mechanical properties and deformation behavior of SiCp/2024Al composites

Cailiao gongcheng
SiCp/2024Al composite was prepared by semi-solid stirring casting, and the distribution of SiCp was regulated by multi-step deformation of hot extrusion and multi-direction forging (MDF).

Influence of thermomechanical processing on coarse particles, grain structure, and mechanical properties of Al–Cu alloy rings

Journal of Materials Research and Technology, 2023
Rings made of 2219 Al alloy are typically manufactured by multi-directional forging (MDF) and ring rolling at 460 °C, followed by heat treatment. However, this process often results in coarse elongated grains and a large number of coarse Al2Cu particles,

Changes of Microstructures and Mechanical Properties in Commercially Pure Titanium after Different Cycles of Proposed Multi-Directional Forging

Metals, 2019
A newly proposed multi-directional forging (MDF) was successfully applied to a commercially pure titanium (CP Ti). Severe plastic deformation would result in significant and complex changes of microstructure and mechanical properties, so microstructure ...

What characterises well‐connected schools? Exploring centrality in inter‐organisational school networks

British Educational Research Journal, EarlyView.
Abstract Within the educational literature, inter‐organisational school networks are commonly considered instruments for administration, management, and school improvement, but are rarely scrutinised as objects of study themselves. Conversely, in organisational studies, this perspective is given more prominence.

Enhanced Selectivity of Chalcogen Bonding over Halogen Bonding Catalyzed C‐glycosylation Through Differentiated Intermediate Activation

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
By harnessing chalcogen bonding (ChB) catalysis, an exclusive access into a highly stereoselective strain‐release C‐glycosylation pathway was discovered. This was surprisingly not replicable by the conceptually similar halogen bonding (XB) catalysis.

Ch‐Ch‐Ch‐Ch‐Changes: The Impact of Supply Base Growth, Contraction, and Turnover on Firm Innovation

Journal of Operations Management, EarlyView.
ABSTRACT Modern supply chains are experiencing more disturbances due to regulatory shifts, rising sustainability standards, emerging or declining markets, and disruption to critical inputs. Some firms react by strengthening existing supplier partnerships to resist changes, while others reconfigure relationships with suppliers to embrace changes ...

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.
