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...

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...

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 ...

Formability is the ability of a material to deform without fracturing, and the assessment of this property depends on various factors such as temperature, deformation speed, and stress state. There are two main approaches to determining formability: one is based on testing different materials under controlled stress conditions, and the other on dev...
