The Effect of Solid Boriding Time on the Structure, Hardness and Corrosion Properties of AISI 5140 Steel
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2020)
In this study, AISI 5140 steel samples were borided in an electrical furnace at a temperature of 950 degrees C for 4, 6 and 8 h. Structural examinations, hardness measurement and corrosion tests were performed to determine ...
Long-Term Stability of Ferroelectret Energy Harvesters
(MDPI, 2020)
Cellular polypropylene (PP) has been recently used in energy harvesting applications. In this work, we investigate its viability and long-term stability under various operating conditions. Specifically, the effect of ...
Theoretical and experimental investigation of acoustic performance of multi-chamber reactive silencers
(ELSEVIER SCI LTD, 2020)
The acoustic attenuation and performance analysis for blast flow field inside a silencer is investigated. In this regard, a silencer system is designed to reduce the exhaust noise. The effect of position and the number of ...
Influence of T5 heat treatment on the microstructure and lubricated wear behavior of ternary ZnAl40Cu2 and quaternary ZnAl40Cu2Si2.5 alloysEinfluss der T5 Warmebehandlung auf das Gefuge und das geschmierte Verschleissverhalten von der ternaren ZnAl40Cu2-und der quaternaren ZnAl40Cu2Si2,5-Legierung
(WILEY-V C H VERLAG GMBH, 2020)
A ternary ZnAl40Cu2 and a quaternary ZnAl40Cu2Si2.5 alloys were produced by permanent mold casting and subjected to T5 heat treatment at a temperature of 150 degrees C for 24 hours. The structural, mechanical and lubricated ...
Mechanical and microstructural features of autoclaved aerated concrete reinforced with autoclaved polypropylene, carbon, basalt and glass fiber
(Elsevier Sci Ltd, 2015)
Autoclaved aerated concrete (MC) is a construction material obtained by being pore-forming of the mixture prepared with finely crushed siliceous aggregate lime, water and limestone with the addition of aluminum powder and ...
Microstructural, mechanical and dry sliding wear properties of the MgO reinforced aluminium matrix composites produced by vacuum infiltration
(Redakcia Kovove Materialy, 2014)
Dry sliding wear properties of MgO (10-40 vol.%) reinforced aluminium matrix composites produced by vacuum infiltration method were investigated using a pin-on-disc test machine after examining their microstructural and ...
Effect of Infiltration Pressure on Thermal Conductivity of Al 2014 Matrix Composite Powered by Silicon Carbide
(Asian Journal Of Chemistry, 2012)
By using pressure infiltration method, metal matrix composites are produced by saturating Al 2014 aluminum composite to the gaps among SiC powders. SiC powders filled into stainless steel tubes are fastened between the ...
Clamp fixation to prevent unfolding of a suture knot decreases tensile strength of polypropylene sutures
(Springer, 2012)
Purpose Although sutures evolved in last decade and the product spectrum broadened largely, they can be still classified into two: monofilament and multifilament. Sutures are the mainstay of orthopedic procedures like ...
Investigation of the design of a metal-lined fully wrapped composite vessel under high internal pressure
(Taylor & Francis Ltd, 2010)
In this study, a Type III composite pressure vessel (ISO 11439: 2000) loaded with high internal pressure is investigated in terms of the effect of the orientation of the element coordinate system while simulating the ...
Derivation of empirical equations for thermodynamic properties of a ozone safe refrigerant (R404a) using artificial neural network
(Pergamon-Elsevier Science Ltd, 2010)
This study, deals with the potential application of the artificial neural networks (ANNs) to represent PVTx (pressure-specific volume-temperature-vapor quality) data in the range of temperature of 173-498 K and pressure ...
