Advanced Engineering Materials, EarlyView.This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Random close packing of granular matter
, 2007 We propose an interpretation of the random close packing of granular materials as a phase transition, and discuss the possibility of experimental verification.Comment: 6 ...

Superconducting transition in disordered granular superconductors in magnetic fields [PDF]
, 2006 Motivated by a recent argument that the superconducting (SC) transition field of three-dimensional (3D) disordered superconductors with granular structure in a nonzero magnetic field should lie above $H_{c2}(0)$ in low $T$ limit, the glass transition (or,

Advanced Engineering Materials, EarlyView.This study investigates laser metal deposition of aluminum alloys EN AW‐7075 and EN AW‐5083, using powder blending to compensate zinc and magnesium evaporation. In situ alloying and ex situ alloying with ZnAl12 and AZ91 preserve near‐standard compositions and improve mechanical properties.

Pore collapse during impacts in granular materials [PDF]
EPJ Web of ConferencesThe rapid compaction of grains and pores during the initial stages of impact into granular materials controls crater formation and ejecta release. In hydrocode modeling of these impacts, pore collapse is assumed to occur homogeneously throughout the ...

Magnetic resonance imaging of granular materials [PDF]
Review of Scientific Instruments, 2017 Magnetic Resonance Imaging (MRI) has become one of the most important tools to screen humans in medicine; virtually every modern hospital is equipped with a Nuclear Magnetic Resonance (NMR) tomograph. The potential of NMR in 3D imaging tasks is by far greater, but there is only “a handful” of MRI studies of particulate matter.

Advanced Engineering Materials, EarlyView.Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.

Ultrasound Induces Aging in Granular Materials
Physical Review Letters, 2012 Aging and rejuvenation have been identified as the general mechanisms that rule the time evolution of granular materials subjected to some external confinement pressure. In creep experiments performed in a triaxial configuration, we obtained evidence that relatively high intensity ultrasound waves propagating through the material induce both weakening ...

Advanced Engineering Materials, EarlyView.The study investigates novel semi‐finished products made of unidirectionally arranged hemp or pineapple leaf fiber‐reinforced composites produced from different matrices. The materials are analyzed in terms of their mechanical and interfacial properties and void content.
