This project investigated the potential of using dolomite from Central Bosnia as a raw material for high-purity metallic magnesium production. Extensive sampling and mineralogical analyses revealed the suitability of these deposits, particularly for methods like the Pidgeon Process. Preliminary results underscored the strategic value of Bosnia&rsqu...

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 ...

The paper presents the results of a microstructural analysis of copper alloys produced in the Copper Mill Sevojno. The analyzed materials comprise high-purity copper (Cu-ETP and Cu-DHP) and a series of brass alloys with varying zinc content (CuZn10, CuZn15, CuZn28, CuZn30, CuZn33, CuZn37). Various thermomechanical treatments were conducted on the s...

The Cu-Al-Zn alloy is used as a functional material in industry, and also as a biomaterial. These alloys have excellent electrical properties, good thermal conductivity, and can also be used for biomedical purposes.The basic characteristic of alloys that remember their shape is their independent return to some of their remembered shape when the tem...

There is a significant increase in industrial applications of ferritic high-Si ductile cast irons (3 - 6%Si), such as the automotive and maritime industries, wind power technology and mechanical engineering. Ferritic high-Si ductile cast irons replace un-stable mixed ferrite-pearlite matrix, with a unique combination of high elongation, strength an...

The changes in pH and conductivity during the rinsing of the pumpkin peel, and the biosorption of Cu2+ ions, were the subject of this work. The obtained data showed that the pH value of the solutions increased during the rinsing of the biosorbent, as a result of the transfer of H+ ions from the aqueous phase into the structure of the pumpkin peel. ...

Ferrochrome slag is a by-product of ferrochrome alloy production, which is an important component of stainless steel.  The total production of ferrochrome slag, which increases significantly every year with the increase in stainless steel production, is more than 1.1-1.5 times higher than the production of ferrochrome metal. In order to conser...

In this work, I aim to examine the various influences of process parameters on the physical and mechanical properties of extruded polystyrene (XPS). Since XPS belongs to the group of thermoplastic polymers, its properties are significantly affected by thermal treatment, particularly temperature and pressure. However, in addition to these key factor...

Technological developments and the demand for innovative products in catalysis and energy conversion/storage have driven the development of high entropy alloys (HEAs) and high entropy oxides (HEOs). HEAs, formed by combining four or more elements in nearly equal ratios, and HEOs have become prominent research topics for the above-mentioned technolo...

Specific environmental conditions, such as marine environments, often influence steel applications in marine industries. These conditions are commonly simulated using a NaCl solution in order to simplify the study and eliminate the complexities of seawater's chemical and biological variability. In this study, 42CrMo4 steel samples, a widely utilize...
