Microstructure evolution and mechanical properties degradation of HPNB alloy after an eleven-year service / Mikrostrukturni razvoj i degradacija mehaničkih svojstava legure HPNB posle jedanaest godina eksploatacije
(Society for Structural Integrity and Life (DIVK), 2022)
In this work, the heat-resistant cast steel HP40Nb alloy, produced in the form of a centrifugally cast tube, which failed after 11.4 years service is investigated. The microstructure is examined using a scanning electron ...
Enzymatic lipophilization of vitamin C with linoleic acid: Determination of antioxidant and diffusion properties of L-ascorbyl linoleate / enzimska lipofilizacija vitamina C linolnom kiselinom - određivanje antioksidativnih i difuzionih svojstava L-askorbil-linolata
(Institute for Food Technology, Novi Sad, 2018)
Lipophilic derivatives of vitamin C are additives with antioxidant properties, attractive for application in food, cosmetics and pharmaceutics. They could be synthesized in lipase-catalyzed processes by using various acyl ...
Anodization of Ti-based materials for biomedical applications: A review
(Association of Metallurgical Engineers of Serbia, 2016)
Commercially pure titanium (cpTi) and titanium alloys are the most commonly used metallic biomaterials. Biomedical requirements for the successful usage of metallic implant materials include their high mechanical strength, ...
Organoclay-polymer nanocomposites / Organoglina-polimerni nanokompoziti
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The properties of polymer nanocomposites exceed the properties of common composite materials due to the nanoscale size and morphology of the fillers used. Particulate fillersare commonly used in polymers forimproved ...
Micromechanical fracture analysis of laminated glass-epoxy composite material tested by bending / Mikromehanička analiza loma laminatnog staklo-epoksi kompozitnog materijala ispitivanog savijanjem
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The object and purpose of this work is the micromechanical analysis of failures caused by mechanical tests of laminate glass-epoxy composite material in bending. The structure of glass-epoxy composite material is a glass ...
Integrity assessment of vital beam components that enable conjoint operation of two bridge cranes
(Society for Structural Integrity and Life, Institute for Material Testing, 2018)
Vital components of the beam that enable conjoint operation of two bridge cranes are braces and threaded spindle. The beam connects two bridge cranes with overall lifting capacity of 500 t (2 x 250 t) and enables their ...
Optimizing the thermal gradient and the pulling speed in a thermoplastic pultrusion process of pet/e glass fibers using finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2018)
A thermoplastic pultrusion process was examined using commercial fiber roving of PET/E glass, to determine the optimum pulling speed and optimal zonal temperatures. Finite element analysis predicted heat transfer through ...
Nanotubular oxide layers formed on the ti-based implants surfaces-application and possible damages: a review
(Savez inženjera metalurgije Srbije, Beograd, 2018)
Implant surface properties define the interaction of the implant with the surrounding tissue. To obtained advanced biological, mechanical and physical properties, metallic implants are often exposed to different kinds of ...
Influence of defects on limit loads and integrity of the pipeline at hydropower plant 'Pirot'
(Society for Structural Integrity and Life, Institute for Material Testing, 2020)
Topic of this work is the integrity assessment of the pipeline section from hydropower plant Pirot. Crack-like defect size, maximum depth, is determined based on non-destructive evaluation - the largest crack depth is taken ...
Prednosti zavarivanja trenjem sa mešanjem u odnosu na elektrolučno zavarivanje - zaštita zdravlja i životne sredine i bezbednost na radu / Advantages of friction stir welding over arc welding with respect to health and environmental protection and work safety
(Society for Structural Integrity and Life (DIVK), 2015)
U savremenoj industrijskoj proizvodnji, svaki proizvodni proces treba da bude ispitan u pogledu uticaja na životnu sredinu. Za svaku kompaniju koja investira u novi proces je od značaja pažljivo razmatranje HSE (Health, ...
