DUCTILITY CAPACITY STUDY OF LARGE-SCALE, BUCKLING-RESTRAINED BRACES IN STEEL STRUCTURES
One of the new methods of anchoring steel structures is the use of large-scale buckling-restrained braces (BRBs) on the lateral system of this type of structures. This study investigates the behavior of BRBs and compares them with buckling braces. In this study, a two-dimensional frame with four stories and four spans was taken and analyzed...

INFLUENCE OF CORROSION ON MECHANICAL CHARACTERISTICS OF STEEL SAMPLES (42CrMo4)
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 EFFECT OF CHLORIDE IONS ON THE CORROSION CHARACTERISTICS OF Cu-Al-Zn BIOALLOY
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...

ANALYSIS OF FORMABILITY IN BENDING USING SOLIDWORKS SOFTWARE
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...

CONTRIBUTION TO INVESTIGATION OF THE INFLUENCE OF WELDING ON THE HARDNESS AND MICROSTRUCTURE OF SUPERALLOY NIMONIC 80A
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 ...

MICROSTRUCTURAL ANALYSIS OF COPPER ALLOYS WITH DIFFERENT ZINC CONTENT
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...
