Picosecond Laser Shock Peening of Nimonic 263 at 1064 nm and 532 nm Wavelength
(MDPI, Basel, 2016)
The paper presents a study on the surface modifications of nickel based superalloy Nimonic 263 induced by laser shock peening (LSP) process. The process was performed by Nd3+:Yttrium Aluminium Garnet (YAG) picosecond laser ...
Experimental investigations of flow distribution in coolant system of Helium-Cooled-Pebble-Bed Test Blanket Module
(Elsevier Science Sa, Lausanne, 2016)
This paper deals with investigations of flow distribution in the coolant system of the Helium-Cooled Pebble -Bed Test Blanket Module (HCPB TBM) for ITER. The investigations have been performed by manufacturing and testing ...
Creep crack growth properties of P91 and P22 welded joints
(Wiley, Hoboken, 2017)
The ferritic P22 and bainitic-martenstic P91 steel welded joints operating at elevated temperatures are highly vulnerable to premature failure, because microstructure gradients can lead to cracking in the heat-affected ...
Stringer effect on fatigue crack propagation in A2024-T351 aluminum alloy welded joint
(Elsevier Sci Ltd, Oxford, 2017)
This paper describes fatigue crack growth in a friction stir welded T joints made of aluminum alloy A2024-T351 under three point bending loads. For this purpose, three dimensional homogeneous isotropic model is used to ...
Ductile fracture of pipe-ring notched bend specimens - Micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Integrity of pipes is typically assessed by testing fracture mechanics specimens, such as compact tensile (CT) or single-edge notched bending (SENB). However, for some pipe dimensions it is not easy or possible to fabricate ...
Influence of welded joint microstructures on fatigue behaviour of specimens with a notch in the heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, the results of determining the Paris law coefficients, C and m, are presented, based on the experimental data obtained by three-point bending testing of 8 welded joint specimens. The specimens were taken ...
Utilization of waste ceramics and roof tiles for radionuclide sorption
(Inst Chemical Engineers, Rugby, 2017)
The possible utilization of waste ceramic (CT) and roof tiles (RT), as sorbents for liquid radioactive waste (LRW) treatment, was investigated. Following the European directives on waste and politics of saving natural raw ...
Integrity assessment and determination of residual fatigue life of vital parts of bucket-wheel excavator operating under dynamic loads
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper are presented results of tests and analyses of complex dynamic loads carried out on the bucket-wheel excavator SchRs 650/5x24 Krupp, as well as assessment of service life of vital welded structures of a ...
Design of capacitive voltage divider for measuring ultrafast voltages
(Elsevier Sci Ltd, Oxford, 2018)
The aim of this paper is to consider and analyze design of capacitive voltage divider for measuring ultrafast voltage occurrence. Measuring pulse voltages by means of a capacitive divider in nanosecond range is affected ...
Load-bearing steel structure diagnostics on bucket wheel excavator, for the purpose of failure prevention
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The appearance of cracks on load-bearing steel structure of compact, hydraulic bucket wheel excavator was a perennial problem. Unfavourable stress concentration, inadequate geometry and structure of materials, inadequate ...
