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), ...
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 ...
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 ...
New types of protective coatings and development of test methods
(Structural integrity and life, 2023)
The paper presents the results of synthesis and charac-terisation of refractory coatings based on various fillers intended for the protection of metallic structures. Refractory fillers applied are based on mullite, cordierite, ...
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 ...
Crack tip fields effects on crack propagation through the heat affected zone in an overmatched welded joint
(2023)
The mismatching constraint effect on crack propagation through the heat-affected zone (HAZ) in a welded joint is presented in this paper. It is shown that due to this effect, the fracture behavior of an overmatched welded ...
Life Assessment of Corroded Wire for Prestressing
(MDPI, 2023)
The repair of structural elements for the prestressing of reinforced concrete is necessarywhen existing prestressing wires are damaged or after a certain period of time. The objective of thispaper is to describe the ...
