Explosive boiling of water films based on molecular dynamics simulations: Effects of film thickness and substrate temperature
(Elsevier, 2023)
This paper deals with investigations of mechanisms governing explosive boiling of water films on hot copper substrate with plain surface. The investigations are based on results of molecular dynamics (MD) simulations in ...
Erosion Wear Behavior of High Chromium Cast Irons
(Springer, 2023)
In this study, two high chromium cast irons
(HCCI) with different chromium content (15%Cr and
25%Cr), in as-cast and annealed conditions (heat-treated,
HT), were tested to determine the erosion wear behavior of
these ...
Increased hydraulic resistance in tubes of once-through boiler due to fouling: A case study of 650 MWe ligite fired unit
(Elsevier, 2023)
The analysis of pressure changes in water and steam flow along the entire once-through steam boiler tube system at the 650 MWe lignite fired Unit was carried out after the long operational period of almost 30 years without ...
Effect of building direction and heat treatment on mechanical properties of Inconel 939 prepared by additive manufacturing
(Springer Nature, 2023)
This study investigated the effect of building direction (BD) and three-step heat treatment on the microstructure and mechanical properties of a nickel-based superalloy Inconel 939 produced by additive manufacturing (AM), ...
Integrity of Welded Joints Made of Alloy NiCr21Mo
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, Institut za ispitivanje materijala (IMS), Beograd, 2023)
The research covers the investigation of mechanical properties of welded joint made on NiCr21Mo alloy (commercial trademark Incoloy 825), and joints of steels P355GH and X2CrNiMo17-12-2, as well as the influence of the ...
Environmental, social and other non-profit impacts Of mountain streams usage as Renewable energy resources
(Technical Institute of Bijeljina Republic of Srpska - Bosnia and Herzegovina, 2023)
The main subject of this manuscript is mountain streams used by construction of small hydro power plants. The motivation for this research stemmed from a number of conflicting opinions about the justification of the ...
Development and Improvement of Numerical Models of Welded Joints with Multiple Defects
(Trans Tech Publications, 2023)
This paper presents the development of numerical models which were used to simulate
the behaviour of welded joints containing different combinations of multiple defects under tensile
loads. Four representative combinations ...
Impact of residual stress on integrity of the vessel for methanol storing
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, 2023)
The purpose of this paper is to present impact of the improper choice of the procedure for repairing of pressure vessel for methanol storage, which finally could leads even to its failure. Represented information are based ...
INSPECTION OF DAMAGE AND RISK ANALYSIS OF CONTAINERS IN A COAL DRYING FACILITY IN EXPLOITATION
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, Institut za ispitivanje materijala (IMS), Beograd, 2023)
Risk analysis of containers in a coal drying facility was performed using the Failure Modes and Effects Analysis (FMEA) method in combination with the risk matrix. The selected exploitation period analysed for all vessels ...
Printing orientation influence on tensile strength of PA12 specimens obtained by SLS
(Springer, 2023)
Selective laser sintering (SLS) is one of the additive manufacturing technologies dedicated to the production of high-quality parts with complex geometries. Here, polyamide 12 (PA12) is a commonly used material, for ...
