Use of Frit‐Disc Crucible Sets to Make Solution Growth More Quantitative and Versatile

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The recent availability of step‐edge, frit‐disc crucible sets (generally sold as Canfield Crucible Sets or CCS) has led to multiple innovations associated with the group's use of solution growth. The use of CCS allows for the clean separation of liquid from solid phases during the growth process.

Simulation of metal-oxide melt interaction in view of kinetics of chemical reactions in the interphase boundary [PDF]

The Seventeenth Israeli - Russian Bi-National Workshop 2018. The optimization of composition, structure and properties of metals, oxides, composites, nano and amorphous materials. Ariel, 2018, 273-286, 2018
Thermodynamics analysis of oxidation-reduction reactions between metal melt and slag (1) provides answers to certain practical issues such as the path of specific chemical reactions, final (equilibrium) phase composition, and the elements that are reduced and oxidized at given physical parameters.

Fracture and Damage Analysis of Cement‐Stabilized Fine and Coarse Grain Soils Under Static and Cyclic Loading Using Chevron‐Notched SCB Specimen

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Fracture toughness and cohesive fracturing properties of two classes of sandy‐clay soils, (A) with fine and (B) coarse grains and stabilized with low (2%) and high (10%) cement (as soil stabilizer), were investigated using a chevron‐notched semicircular bend (CN‐SCB) sample under static and cyclic loads.

Waste-based consumable for hardfacing by welding: a look from the Circular Economy

Dyna
In the present work, the obtaining of a consumable for the restore parts by welding from the perspective of the circular economy is addressed, using industrial solid residuals (slag from steel production, graphite from fragments of electrodes of arc ...

Phase formation in the CaO–Al2O3–ZnO system as an analogue to CaO–Al2O3–MgO in spinel containing refractories

Journal of the American Ceramic Society, Volume 108, Issue 5, May 2025.
Abstract Recently, gahnite (ZnAl2O4) is gaining attraction as a potential refractory ceramic because of the similarity of its structure and properties with those of magnesium aluminate (MgAl2O4) spinel refractories. Formation of MgO and hibonite solid solution (CaMgxAl12−xO19−0.5x; 0 ≤ x ≤ 0.18), CAM‐I (Ca2Mg2−3xAl28+2xO46 (0 ≤ x ≤ 0.3), and CAM‐II ...

Effect of nonmetallic inclusions on steel welds metal hot cracking

Metalurgija, 2014
Intercrystally distributed nonmetallic inclusions greatly increase weld susceptibility to hot cracking. Oxide and sulphide inclusions are the result of contaminated base material or its highly oxidised surfaces and they can be a consequence of ...

The Interfacial Characterization and Performance of Cu/Al-Conductive Heads Processed by Explosion Welding, Cold Pressure Welding, and Solid-Liquid Casting

Metals, 2019
The Cu/Al composites conductive head is widely used in hydrometallurgy as the core component of cathode plate. Its conductive properties directly affect the power consumption, and the bonding strength and corrosion resistance determine the conductive ...

Calibrated Fibrations on Complete Manifolds via Torus Action [PDF]

arXiv, 2000
In this paper we will investigate torus actions on complete manifolds with calibrations. For Calabi-Yau manifolds M^2n with a Hamiltonian structure-preserving k-torus action we show that any symplectic reduction has a natural holomorphic volume form.

Weak Crust Owing Past Magmatic Intrusions Beneath Campi Flegrei Identified: The Engine for Bradyseismic Movements?

AGU Advances, Volume 6, Issue 2, April 2025.
Abstract Calderas often experience extended periods of unrest that are challenging to relate to a magmatic or hydrothermal origin, making it crucial to assemble a clear picture of these dynamics. Since 2005, Campi Flegrei caldera (Italy) has experienced accelerating ground uplift, seismicity rates, and degassing.

Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects

Strain, Volume 61, Issue 2, April 2025.
ABSTRACT There are limited data on the very high‐cycle fatigue for structural steel welds for over 10 million cycles. The purpose of this research is a fatigue performance comparison of the welds made of steels S355JR+AR and S275JR+AR. The goal of reaching the gigacycle fatigue domain is achieved using the ultrasonic fatigue testing at 20 kHz.
