Abstract:

The microscopic size effect of microhardness that we have found earlier for electrodeposited binary alloys of tungsten and the iron group metals is explained here by an increased concentration of oxygen-containing impurities in the coatings, revealed for Co-W alloys. An increase in oxygen-containing impurities correlates with the volume current density (VCD), meaning that microhardness of electrodeposited alloys diminishes at a higher VCD. The properties of the coatings  (e.g., microhardness) are also affected by the nature of the anode used, since the complex from which electrodeposition

Abstract:

Fabricating by growing electro-active species on conductive substrates improves active site exposure without needing binders. Electro-deposition, a cost-effective method, enables in-situ deposition of non-precious metal catalysts on substrates like carbon paper and nickel foam. This approach enhances activity and stability for reactions such as hydrogen evolution, oxygen evolution, and CO₂ reduction.1 This research presents the first confirmed synthesis of a tungsten–copper (Cu–W) alloy via pulsed galvanic electrodeposition.

The possibility of improving the characteristics of a dry sliding electrical contact with a current density higher than 100 A/cm2 by using a molybdenum counterbody is considered. It is shown that tungsten or metallic materials containing bearing steel (1.5 % Cr) in sliding against molybdenum at a speed of 5 m/s under electric current, forms a contact with low electrical conductivity and high wear intensity. This observation served as the basis of this work. Using optical and electron microscopy of sliding surfaces it was found that strong adhesion in the interface was the main reason for rapid

Abstract:

The range of iron-based materials known as stainless steels are used throughout the world to manufacture products requiring special resistance to corrosive environments. The corrosion resistance of these materials depends largely upon the chromium content, which is usually between 10 and 30 per cent of the alloy constitution. Of equal significance is the ability to vary the structure of the alloy between ferritic, austenitic and martensitic, by control of the type and level of additional elements. There are, however, many corrosion limiting factors which restrict the use of each type of steel,

The amorphous phase content of the alloy increases with decreasing crystal grain size. As the amorphous phase content increases, the magnetization, electrical conductivity and hardness of the alloy decrease.

The reduction of tungstate and molybdates ions in aqueous solution is often referred as induced codeposition. Those ions can only be reduced to a metallic state alongside another element.

Cobalt and iron, sharing many properties with nickel, are also reported as inducing element for Tungsten and or Molybdenum codeposition [2].

Sulfur, an element that belongs to group 16 (chalcogens) of the periodic table, is an excellent promoter of nucleation substrates for graphite in cast iron.

It is reasonable to expect that other elements from group 16, such as selenium or tellurium, play similar roles in the nucleation of graphite.

Abstract:

As society works towards reducing its carbon footprint, various sectors such as energy, steelmaking and fertilizer production have begun to look increasingly towards decarbonization. Hydrogen production through electrolysis, when linked to renewables (solar, wind), provides a promising low-emission alternative as an energy carrier and chemical feedstock. With the decreasing cost of said renewables, greater focus is now on the capital cost of the electrolyser, and particularly the membrane/electrode structures. Conventional Proton Exchange Membrane (PEM) electrolysers rely on the use of electro

Chlorine and a material with similar or lower electropositive, typically a metal or a mineral oxide, are combined to form chromium at temperatures between 1,000 and 2,800 °C (1,800 and 5,100 °F). Any nitride can be made using one of multiple common techniques. When milling hard materials like carbon steel or wrought iron, or in situations when steel tools would soon wear out, such as in high-volume, mass yield, cutting tools edges are frequently utilised. The compound known as carbide is made up of oxygen and metals or semi-metallic components. It is present in ionic form. The ionic or covalen

Abstract:

A mechanism is proposed for the nucleus formation at the mutual transformation of austenite and cementite crystals. The mechanism is founded on the interpretation of the considered structures as crystallographic tiling onto non-intersecting rods of triangulated polyhedra. A 15-vertex fragment of this linear substructure of austenite (cementite) can be transformed by diagonal flipping in a rhombus consisting of two adjacent triangular faces into a 15-vertex fragment of cementite (austenite). In the case of the mutual austenite–cementite transformation, the mutual orientation of the initial and

Neodymium iron borate NdFe3(BO3)4 is an intensively studied multiferroic with high electric polarization values controlled by a magnetic field. It is characterized by a large quadratic magnetoelectric effect, rigidity in the base plane and a rather strong piezoelectric effect. In this work, the atomic structure of (Nd0.91Bi0.09)Fe3(BO3)4 was studied by single-crystal X-ray diffraction in the temperature range 20–500 K (space group R32, Z = 3). The Bi atoms found in the composition partially substitute the Nd atoms in the 3a position; they entered the structure due to the growth conditions in t

Abstract:

A part of the system CaO-SiO2–Al2O3–Fe2O3–MgO which is of relevance to iron-ore sintering has been studied in detail. For a bulk composition corresponding to 10.45 wt% CaO, 5.49 wt% MgO, 69.15 wt% Fe2O3, 13.37 wt% Al2O3 and 1.55 wt% SiO2 synthesis runs have been performed in air in the range between 1100 and 1300°C. Products have been characterized using reflected-light microscopy, electron microprobe analysis and diffraction techniques. At 1250°C, an almost phase-pure material with composition Ca2.99Mg2.67Fe3+ 14.58Fe2+ 0.77Al4.56Si0.43O36 has been obtained. The compound corresponds to the fi

This lecture presents the authors personal views on the landmark events that have strongly affected the welding of stainless steels over their lifetime. Although 1913 is commonly recognized as the birth of stainless steels with the commercialization of the martensitic alloy of Harry Brearly and the austenitic alloy of Eduard Maurer and Benno Straus, the story can be considered to begin as long ago as 1797 with the discovery of chromium by Klaproth and Vauquelin, and the observation by Vauquelin in 1798 that chromium resists acids surprisingly well.

Abstract:

An accurate single-crystal X-ray diffraction study of bismuth-containing HoFe3(BO3)4 between 11 and 500 K has revealed structural phase transition at T str = 365 K. The Bi atoms enter the composition from Bi2Mo3O12-based flux during crystal growth and significantly affect T str. The content of Bi was estimated by two independent methods, establishing the composition as (Ho0.96Bi0.04)Fe3(BO3)4. In the low-temperature (LT) phase below T str the (Ho0.96Bi0.04)Fe3(BO3)4 crystal symmetry is trigonal, of space group P3121, whereas at high temperature (HT) above 365 K the symmetry increases to space
