In-Line Dimensional Inspection of Warm-Die Forged Revolution Workpieces Using 3D Mesh Reconstruction

Applied Sciences, 2019
Industrial dimensional assessment presents instances in which early control is exerted among “warm” (approx. 600 ∘C) pieces. Early control saves resources, as defective processes are timely stopped and corrected.

AA7050 Al Alloy Hot-Forging Process for Improved Fracture Toughness Properties

Metals, 2019
The conventional heat-treatment standard for the industrial post hot-forging cycle of AA7050 is regulated by the AMS4333 and AMS2770N standards. An innovative method that aimed to improve toughness behavior in Al alloys has been developed and reported ...

Effect of Surface Treatment on Warm Forging Die

DENKI-SEIKO[ELECTRIC FURNACE STEEL], 2007
Recently, a warm forging process is remarkable from the points of view in near net shaping and abolishment of additional heat treatment by micro-structural controlling. In generally, a die life in forging decreases accompany with the increase of forging temperature. The die life in hot forging is only about 1/10∼1/100 compared with that in cold forging,

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils

Advanced Science, EarlyView.
We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet

Influence of deformation on the kinetics of phase transformation in a forging steel during warm working

Materials Research, 2004
Dilatometric techniques were used to determine the start and finish transformation heating temperatures for a carbon steel (0.30% C - 1.5% Mn). The mechanical behavior of the steel was measured by torsion testing in the temperature range of 700 to 820 °C

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

Advanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

Large Language Model‐Informed Dual‐Track AI Framework for the Synergistic Design of Crack‐Free and High‐Strength Superalloys

Advanced Science, EarlyView.
This paper illustrates a knowledge‐augmented dual‐track AI framework for advanced superalloy design. First, Large Language Models translate metallurgical heuristics into explicit rules to rapidly prune a vast compositional search space. Subsequently, LLM‐distilled priors safely guide a reinforcement learning agent during autonomous process optimization,

The situated professional: Preservice teachers' profiling of globally competent teachers and visions of their ‘possible professional self’

British Educational Research Journal, EarlyView.
Abstract In response to globalisation, teacher education programmes worldwide are tasked with preparing globally competent teachers (GCTs). Prevailing conceptions of global competence are largely derived from Western‐centric humanistic, neoliberal and transformative narratives, creating a complex landscape for teacher identity formation.

Beyond Conventional Cost–Benefit Analysis to Integrated Sustainability Assessment in Additive Manufacturing

Business Strategy and the Environment, EarlyView.
ABSTRACT Additive manufacturing (AM) adoption provides numerous benefits, including decentralised production, design flexibility, mass customisation, reduced material waste and lightweight designs. However, AM investment decisions are complex and challenging for manufacturers, and limited knowledge exists about the holistic assessment of relevant costs

Towards Transformative Climate Governance: Capacities and Constraints for Local Government in Aotearoa New Zealand

Environmental Policy and Governance, EarlyView.
ABSTRACT An emerging consensus calls for transformative climate governance. However, what instigates and sustains transformative pathways remains unclear. This study characterises the existence, quality and structural underpinnings of transformative governance capacities in local government climate change response in Aotearoa New Zealand, applying a ...
