Dual Phase Austempered Ductile Iron - The Material Revolution and Its Engineering Applications
(Springer International Publishing Ag, Cham, 2020)
During the last few years, there has been an increased interest in improving the strength of ductile iron by means of heat-treating to obtain dual phase microstructures that enhance the properties found in the Austempered ...
Risk assessment of oil drilling rig welded pipe based on structural integrity and life estimation
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Risk assessment procedure based on structural integrity and life estimation has been introduced and applied to oil drilling rig welded pipe. The new concept based on application of structural integrity and life estimation ...
Economic Implications of Innovative Visual Guidance System for Crane Cabins
(Springer, 2020)
This paper proposes innovation through implementation of a real-time computer-aided visual guidance system (VGS) which prevents crane accidents, caused by crane operator’s obstructed view, which can be the cause of collisions ...
Corrosion behaviour of AA2024 aluminium alloy in different tempers in NaCl solution and with the CeCl3 corrosion inhibitor
(Wiley-V C H Verlag Gmbh, Weinheim, 2020)
The paper analyses the corrosion behaviour of naturally and artificially aged AA2024 alloy in NaCl solution and in the presence of an environment-friendly corrosion inhibitor, CeCl3. On the basis of the values of polarisation ...
Determination of the optimal production plan by using fuzzy AHP and fuzzy linear programming
(IOS Press, Amsterdam, 2020)
In this paper, we consider the problem of determining the optimal production quantity under uncertainties. The treated problem has a critical effect on the achievement of business goals, which further propagates to the ...
Engineering critical assessment of steel shell structure elements welded joints under high cycle fatigue
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Existing flaws in critical parts of structural elements may lead to failures of subassemblies and, in case of lack of redundancy, even to the entire structure collapse. Considering the case of cyclic loading - wind load ...
Experimental verification of performance of tip-jet helicopter propulsion system
(Elsevier, Amsterdam, 2020)
This paper presents the methodology for estimation of power delivery and efficiency of the tip-jet helicopter propulsion system. The main advantage of the tip-jet helicopter is the absence of heavy transmission and tail ...
Thermomechanical behavior of bio-fiber composite thermal insulation panels
(Elsevier Science Sa, Lausanne, 2020)
The thermomechanical properties of the bio-fiber composite, as material for the production of thermal insulation panels, were evaluated. The observed mixtures were composed of Miscanthus x giganteus bio-fibers, mineral ...
Effect of laser shock peening with and without protective coating on the microstructure and mechanical properties of Ti-alloy
(Elsevier Sci Ltd, Oxford, 2020)
Owing to their good mechanical properties, titanium based alloys are used for machine parts and devices that operate in demanding regimes and environmental conditions. Laser shock peening (LSP) is an innovative technique ...
Microstructure and Wear Behavior of MMC Coatings Deposited by Plasma Transferred Arc Welding and Thermal Flame Spraying Processes
(Springer India, New Delhi, 2020)
In this study, two erosion protection MMC coatings with WC particles were deposited by the plasma transferred arc (PTA) welding. One of the coatings with tungsten carbide WC in the NiBSi matrix (WC/NiBSi), and the second ...
