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, ...
An investigation on optimum grinding system and conditions for steel plant ARP by-product α-Fe2O3 for pigment industry
(Elsevier, 2020)
After some other processes, α-Fe2O3 red powder particles -by-product of regeneration of spent pickling liquor in ARP in iron and steel industry- should be ground up to pigment grade to convert it to a value added product, ...
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 ...
Exergetic Simulation and Performance Analysis of the Effect of Flow Patterns in PEMFCs
(Int Center Applied Thermodynamics, 2019)
In this study, 6 different novel flow channels of the "proton exchange membrane" (PEM) type fuel cells were designed and modeled, while evaluations were conducted on three-dimensional channels of various designs using ...
Improving Autonomous Performance of a Passive Morphing Fixed Wing UAV
(Kauno Technologijos Universitetas, 2020)
In this article, simultaneous longitudinal and lateral flight control systems design for both passive and active morphing unmanned aerial vehicles (UAVs) is first time applied for autonomous flight performance maximization. ...
Parametric Optimisation of an ORC in a Wood Chipboard Production Facility to Recover Waste Heat Produced from the Drying and Steam Production Process
(Mdpi, 2019)
The wastes in wood industries (waste chips) are commonly used as fuel for burners to produce steam and to use the remaining heat in the drying process. However, in spite of that, there is a considerable amount of heat ...
Finite element analysis of structures with extruded aluminum profiles having complex cross sections
(Brazilian Association of Computational Mechanics, 2016)
Extruded aluminum profiles are widely used in building and automation structures due to their durability, lightweight, corrosion resistance, shorter fastening time and reusability. Proper design is crucial in maintaining ...
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), ...
Electricity production by wet type top-pressure recovery turbine in blast furnaces
(Pamukkale Üniversitesi, 2020)
Today, the iron and steel industry is critical to energy consumption. The high energy demand of the iron and steel production process brings along high costs. This leads to the need to reduce energy demand and develop ...
