Applicability of friction stir welding to steels
(International OCSCO World Press, 2017)
Purpose: The friction stir welding (FSW) method is widely considered to be one of the most significant developments in joining technology to emerge in the last 30 years. The technique has originally been developed for ...
Recent developments in joining of aluminum alloys
(Springer, 2017)
The mass saving potential of light-weight materials, such as Al alloys, is beneficial for fuel economy and reducing CO2 emissions. However, the wide-spread use of these alloys has been long hindered due to the difficulty ...
Dry sliding wear behavior of bonded hot-work tool steel at elevated temperatures
(Elsevier Science, 2017)
In the present study, the surface of AISI H13 hot-work tool steel was bonded with EKabor II powders using powder pack-bonding method. The process was carried out at 800,900 and 1000 degrees C temperatures for 2,4 and 6 h ...
Microstructure and mechanical properties of borided inconel 625 superalloy
(Universidade Federal do Rio de Janeiro, 2017)
The Ni-based superalloy Inconel 625 is extensively used owing to its high strength, excellent fabricability, good weldability and outstanding resistance to high temperature corrosion against aggressive environments. However, ...
Flap-wise and chord-wise vibrations of axially functionally graded tapered beams rotating around a hub
(Academic Press, 2017)
This paper presents flap-wise and chord-wise flexural vibration analyses for centrifugally. stiffened tapered beams made of functionally graded material in axial direction. Functions of material properties varying along ...
Microabrasion Wear Behavior of Fast-Borided Steel Tooth Drill Bits
(Taylor and Francis Inc., 2017)
In this study, the surface of steel tooth drill bits (Ni-Cr-Mo based) was subjected to the solid-state boriding treatment with 10- to 50-nm nanoboron powder. Boriding processes were carried out at a constant temperature ...
Effect of borotitanizing on microstructure and wear behavior of Inconel 625
(Elsevier, 2017)
Inconel 625, a nickel-based superalloy, is used in a wide range of applications including the marine and petroleum industries under where it is subjected to harsh conditions such as high temperatures and highly corrosive ...
Extremely-broad band metamaterial absorber for solar energy harvesting based on star shaped resonator
(Springer, 2017)
A new metamaterial absorber (MA) is investigated and shown numerically for solar energy harvesting for future solar cell applications. The structure consists of two metals and one dielectric layer having different thicknesses. ...
Farklı bor kimyasalları ile borlanmış Inconel 625 alaşımının karakterizasyonu
(Pamukkale Üniversitesi Mühendislik Bilimleri Dergisi, 2017)
Bu çalışmada, nikel bazlı süper alaşımlar içerisinde endüstride yaygın olarak kullanılan Inconel 625 alaşımı 3 farklı borlama tozu ile borlanmıştır. Kullanılan borlama tozları, %90 elementel nano bor tozu + %10 NaBF4 (NB), ...
Friction stir welding of AZ31 magnesium alloys – A numerical and experimental study
(Brazilian Association of Computational Mechanics, 2017)
In this paper, weldability of magnesium alloys by friction stir welding (FSW) method which is difficult to join by the fusion welding have been investigated experimentally and numerically. To this end, the connection of ...
