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 ...
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 ...
Effects of Multiple Defects on Welded Joint Behaviour under the Uniaxial Tensile Loading: Fem and Experimental Approach
(MDPI, 2023)
The research represents the ongoing investigation of the welded joints behavior made
of low-carbon low-alloyed steel in the presence of different multiple defects. Following the initial
experimental and numerical analyses ...
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 ...
SIZE EFFECT ASSESSMENT OF KJc EXPERIMENTAL DATA USING THE TWO-STEP-SCALING METHOD
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, Institut za ispitivanje materijala (IMS), Beograd, 2023)
The phenomenon of ductile-to-brittle transition (DBT) in ferritic steels, widely used in design of nuclear reactor pressure vessels, has been a pervasive semi-centennial research topic. Due to the extremely pronounced ...
Ductile-to-brittle transition of ferritic steels: A historical sketch and some recent trends
(Engineering Fracture Mechanics, 2023)
The phenomenon of ductile-to-brittle transition in ferritic steels has been a ubiquitous research challenge for the last 50 years. The characterization of this problem using the fracture mechanics concept, from the earliest ...
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 ...
