Fuels are substances that release heat energy during combustion due to the oxidation process that occurs. In order for a substance to serve as fuel, it is important that it has a high calorific value, which is most affected by the carbon content. Sulfur has a very small effect on this characteristic of the fuel but is considered as a negative compo...

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 ...

Aluminum dross contains high amount of metallic Al (up to %60 wt. Al) and regarded as a waste in aluminum casting operations. High metallic value in Al dross can be utilized via recycling procedure. In this study, Al dross was used in aluminothermic ferrochromium production with chromite ore and mill scale. Enthalpy, Gibbs Free Energy and Entropy o...

In this research, the resulsts of bentonite characterization by XRF before and after adsorption are presented. The influence of temperature and pH on the capacity and efficiency of adsoption of lead (II) ions using bentonite is determined by adsorption experiments for initial lead (II) concentrations of 200, 300 and 400 mg/L, adsorbent dosage of 1 ...

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...

The study investigates the Portevin–Le Chatelier (PLC) effect in the cold rolled Al-Mg alloy EN AW-5754. The tensile tests were performed on dog bone specimens at test speeds of 10, 20 and 50 mm/min. Digital image correlation (DIC) and infrared thermography were used to monitor strain rate and temperature changes. The results showed a strong ...

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...

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...
