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...

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...

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 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. ...

Lightweight concrete is increasingly utilized in sustainable construction due to its reduced weight and improved thermal performance. However, replacing conventional aggregates with alternative lightweight materials may result in a reduction in concrete strength. To address this issue, fiber reinforcement has been introduced to enhance the concrete...

Fillers play a crucial role in enhancing product performance and reducing production costs. To be used in various industries, fillers must be readily available, affordable, pure, non-toxic, and meet specific physical and chemical standards. This study examines limestone and dolomite fillers, focusing on their chemical composition, mineralogical pro...

This paper investigates the effects of oil quenching and tempering at various temperatures on the mechanical and structural properties of X155CrVMo12-1 tool steel. The steel specimens were austenitized at 1030 °C for half an hour, followed by quenching and tempering at different temperatures. Mechanical properties were assessed by measuring the...
