Numerical Model and Experimental Validation of Composite Metal Foam in Protecting Carbon Steel Against Puncture

open access: yesAdvanced Engineering Materials, EarlyView.
The puncture prevention and energy absorption performance of composite metal foam (CMF) are studied experimentally and numerically for hazardous materials transportation protection. The numerical model implementing air within the CMF (nonhomogeneous model using fluid cavity technique) predicts puncture more accurately compared to the homogeneous CMF ...

The Filmmaker as Metallurgist: Political Cinema and World Memory

open access: yesFilm-Philosophy, 2016
Compared to earlier waves of political cinema, such as the Russian revolution films of the 1920s and the militant Third Cinema movement in the 1960s, in today's globalized and digital media world filmmakers have adopted different strategies to express a ...

LiVO3/LiZnVO4 Nanocomposite: High Performance Electrocatalyst for Ambient Nitrogen Reduction to Ammonia

open access: yesAdvanced Engineering Materials, EarlyView.
Lithium‐mediated electrocatalysis enables sustainable N2 fixation but hindered by parasitic Li deposition. An oxide‐oxide nanocomposite (LiVO3/LiZnVO4) structurally integrates lithium into active sites, suppressing plating and enhancing N2 activation and HER supression.

Direct Recycling of Cold Work Tool Steel Swarf into New Cutting Disks via Field‐Assisted Sintering

open access: yesAdvanced Engineering Materials, EarlyView.
Through a sintering method known as field‐assisted sintering technology/spark plasma sintering, cold work tool steel swarf can be directly recycled into new cutting disks. This method is capable of densifying the unconventional powder morphology of swarf, and it can also seal grinding contaminants, such as Al2O3, into the steel matrix.

Formation of Intermetallic Sludge Phases in AlMgSi Alloys with High Concentrations of Alloying Elements: A Drawback for Increasing Sustainability

open access: yesAdvanced Engineering Materials, EarlyView.
Sludge phases with brittle fracture behavior form in AlMgSi alloys with high concentrations of alloying elements and negatively influence their ductility. The phase type mainly depends on the Si content and the concentration of minor alloying elements like Fe, Mn, Cr, and Mo strongly influences the number of sludge particles. The need for sustainable

Production of Metallic Foam Precursors Using Current‐Activated Pressure‐Assisted Densification

open access: yesAdvanced Engineering Materials, EarlyView.
A powder compaction metallurgical method, known as current‐activated pressure‐assisted densification, is applied to enhance the compaction of metal foam precursors. This method improves precursor quality by achieving higher density, lower electrical resistivity, and more uniform pore nucleation in the resulting foams, reducing energy consumption and ...

Innovation technique et rationalisation structurelle dans les centres miniers des cités toscanes et de la couronne d’Aragon

open access: yesMélanges de la Casa de Velázquez, 2018
Among the most characteristic innovations in the genesis of the modern mining enterprise were small-scale assay techniques. There are archaeological remains attesting to the use of such operations in German mining areas from the late 12th century, but ...
