(2018)
In this study mechanical and thermal properties of epoxy resin reinforced withdifferent numbers of nanofiber layers which produced with electrospinning method wasinvestigated. Solution of 10 wt% of polyacrylonitrile (PAN) ...
High temperature wear behavior of the surface-modified externally cooled rolls
(Elsevier, 2018)
Externally cooled rolls of a steel plant were coated using three different surface modification techniques, namely titanizing, boronizing and borotitanizing. The grown coatings were examined using optical microscopy, ...
A Comparative Study on the Effects of Different Thermochemical Coating Techniques on Corrosion Resistance of STKM-13A Steel
(Springer, 2018)
The corrosion resistances of three different thermochemical coatings (grown using titanizing, boriding, and borotitanizing treatments) applied to STKM-13A steel surfaces were investigated. The coatings were characterized ...
Prospects of laser beam welding and friction stir welding processes for aluminum airframe structural applications
(Elsevier Ltd, 2018)
The present study deals with laser beam welding (LBW) and friction stir welding (FSW) applied to high-strength aluminum alloys used in aircraft industry and displays their advantages compared with the riveting technique ...
Boride Layer Growth Kinetics Of Aisi H13 Steel Borided With Nano-Sized Powders
(Polish Academy Sciences, Institute Metallurgy & Materials Sciences, 2018)
Growth kinetics of boride layers in AISI H13 steel was investigated using the pack bonding method at temperatures of 1073, 1173 and 1273 K (800 degrees C, 900 degrees C and 1000 degrees C) for periods of 2, 4 and 6 h with ...
Microstructural and mechanical properties of friction stir welded pure lead
(National Institute of Science Communication and Information Resources (NISCAIR), 2018)
The present study focuses on the applicability of friction stir welding to pure Pb plates. The joint performances are evaluated by optical microscopy, microhardness measurements, notch impact tests and three point bending ...
Microstructure and mechanical properties of friction-stir welded St52 steel joints
(Springer, 2018)
The aim of this work is to investigate the mechanical properties and microstructures of friction-stir welded (FSWed) St52 structural steel joints. In this study, St52 steel plates with a thickness of 4 mm were butt-welded ...
Effects of hydrogenation of fossil fuels with hydrogen and hydroxy gas on performance and emissions of internal combustion engines
(Elsevier, 2018)
Energy security is an important consideration for development of future transport fuels. Among the all gaseous fuels hydrogen or hydroxy (HHO) gas is considered to be one of the clean alternative fuels. Hydrogen is very ...
Mechanical properties of friction stir welded St 37 and St 44 steel joints
(Carl Hanser Verlag, 2018)
In this study, the weldability of lower strength St 37 grade steel plate with a higher strength steel plate (i. e., St 44) using the friction stir welding technique has been studied. St 37 grade steel sheets are widely ...
