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), ...
An approach for automatic free form surface milling machining technology design
(UNIVERSITY OF NOVI SAD, FACULTY OF TECHNICAL SCIENCES, 2023)
Parts with free form surfaces are commonly used in wide area of engineering, not only in mechanical
engineering. When it comes to the area of mechanical engineering, the main problem is how to produce such
parts. One of ...
A METHOD FOR FRACTURE PROBABILITY ASSESSMENT IN FUNCTION OF J-INTEGRAL IN TRANSITION TEMPERATURE REGIME OF FERRITIC STEEL
(University of Belgrade - Faculty of Mechanical Engineering, 2023)
In this paper is presented the 1-point method for material behaviour prediction, in terms of fracture toughness, of the ferritic steel EN 1.6310 in the transition temperature regime (-60°C and -90°C). Experiments were ...
Comparison of two recent approaches to DTB characterization of ferritic steels
(Elsevier B.V., 2023)
The large scatter of the experimental fracture toughness data, characteristic of all ferritic steels in the ductile-to-brittle transition temperature region, imposed the need to include statistical methods for data processing. ...
A NOTE ON THE EFFECT OF STATISTICAL SAMPLE SIZE ON FRACTURE TOUGHNESS CHARACTERIZATION IN THE DTB TRANSITION REGION
(9th International Congress of the Serbian Society of Mechanics (ICSSM), July 5-7, 2023, Vrnjačka Banja, Serbia., 2023)
The ferritic steels, widely used as pressure-vessel materials in nuclear industry, are prone to
embrittlement when exposed to neutron irradiation or temperature reduction within the DTB
(ductile-to-brittle) transition ...
UPGRADED TWO-STEP-SCALING APPROACH TO THE DTB CHARACTERIZATION OF FERRITIC STEELS
(9th International Congress of the Serbian Society of Mechanics (ICSSM), July 5-7, 2023, Vrnjačka Banja, Serbia, 2023)
The fracture toughness of ferritic steels in the DTB (ductile-to-brittle) transition temperature
region is a stochastic extrinsic property known for pronounced experimental data scatter that
necessitates statistical ...
Mechanical characteristics of compressive specimens obtained by SLS technology
(2nd International Symposium on Risk Analysis and Safety of Complex Structures and Components (IRAS 2023), 2023)
The purpose of this research is to investigate the mechanical properties of Additive Manufacturing(AM)parts. The 3D printer used in this study is Fuse 1 (FormLabs, Summerville, MA), which utilizes theSLS(Selective Laser ...
