In this study, aluminum-based composites reinforced with nano-sized boron nitride (BN) were produced by using the casting method. Particle sizes of BN were reduced down to nanoscale via milling for 96 h at room temperature. The casting process ensured a homogeneous distribution of BN within the alloy matrix by melting the aluminum alloy, introducin...

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...

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...

This paper presents some aspects of the correlation between maintenance cost reduction and accidents—specifically, damages due to plastic deformation in steel constructions at production companies in Bosnia and Herzegovina. In the theoretical part, a tension testing diagram for typical structural steels (I, U, T, etc.) is used to explain the ...

The most abundant renewable biomass on the earth is lignocellulosic biomass supplying from the forestry, forestry residue, and agricultural wastes nearly annually 200 billion tones worldwide. Agricultural wastes encompass a lot of cellulose, lignin and hemicellulose in composite form. Cellulose, the most important part of a plant structure, is a re...

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...

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...
