Because of their properties, superalloys are primarily used for the production of structural parts whose operating conditions correspond to elevated temperatures and often extremely aggressive environments. Because of that, they require a combination of high strength, good fatigue and creep resistance, and good corrosion resistance. Nimonic 80A is ...

Titanium and its alloys, particularly Ti6Al4V, are widely used, especially in aerospace andmedicine due to their relatively low density, high strength, and good corrosion resistance. However,there are formidable challenges in casting, forming, and machining titanium alloys, which result infinal products that are considerably more expensive. Additiv...

This article deals with the analysis of the adsorptive properties of the waste produced during theshot blasting of castings in foundries. During this process, particles of moulding mixture andscale that remained on the surface of the casting after removal from the mould are removed. Sincethis waste contains particles of moulding mixture (SiO2, carb...

Many alloys exhibit the shape memory effect, but only the Cu-Al-Zn, Cu-AI-Ni, and Ni-Ti alloysare presentand of commercial importance. The greatest use of these alloys is in biomedicine(filters, orthodontic implants, guide wires for catheters, etc.). Shape-memory alloys may be foundin sensors in automobiles, consumer products, and generally in smar...

Metallic materials in granular packings show different electrical properties from their bulkcounterparts. In this paper, we investigate the temporal evolution of the electrical conductivity ofgranular metals. We use metallic beads arranged in different one-, two- and three-dimensionalensembles through which different constant currents are injected....

The electrocoagulation with zeolite addition was used to treat compost leachate. The effects ofdifferent current densities and zeolite particle sizes on electrode dissolution, electrode surfacecondition, and removal efficiency were investigated. The surface of the electrodes was analysedby optical microscope, while the consumption of the aluminium ...

Considering the toxic properties of heavy metals and their effects on the environment, there is anincreasing interest in studying their interactions with different ligands and searching forpossibilities to remove those ions from the environment. Compared to other ligands, crown etherspossess the highest selectivity as ligands for metal cations, due...
