Aluminium alloy foams are a form of porous metal whose structure resembles the shape of natural materials such as coral, bone, sponge, etc. Due to their structure, these materials retain good mechanical properties of the base material while being significantly lighter than non-porous metal. Metal foams can be used as energy and vibration absorbe...

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...

The paper describes the determination of the mechanical properties of the spherical floors of pressure vessels, obtained by the welding process and shaped by the process of gradual local deformation in the cold state, i.e. by the process of Incremental sheet forming (ISF). Spherical cylindrical bottoms are an integral part of most cl...

In order to examine the state of critical components of the boiler of Unit 5 of Kakanj Thermal Prema wer Plant, headers were tested in order to undertake appropriate technological measures and activities on the basis of insight into the current state of affairs, and to make recommendations for further exploitation. From first commiss...

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...

Heavy metals can enter into rivers through industrial and consumer waste, activities of acidic rainto soils, etc. Long-term exposure can result in damaging: mental and nervous function, bloodcomposition, lungs, kidneys, liver, and other vital organs. Estimating a health risk based on thecontents of heavy metals found in river Bosna was the aim of t...

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...
