Microstructural alteration of alkali activated slag mortars depend on exposed high temperature level
(Elsevier, 2016)
This article reports a study on the microstructural and mechanical properties of the Alkali Activated Slag mortars (MS) upon exposing to the elevated temperatures up to 800 degrees C. Slag cement is activated by sodium ...
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, ...
Properties and Corrosion Behavior of Chromium and Vanadium Carbide Composite Coatings Produced on Ductile Cast Iron by Thermoreactive Diffusion Technique
(ASME, 2020)
Ductile iron (DI) owes many of its attractive mechanical properties to the graphite nodules in its structure. However, since galvanic coupling can occur between the graphite nodules and the matrix in aggressive environments, ...
Properties and High-Temperature Wear Behavior of Remelted NiCrBSi Coatings
(Springer, 2020)
Remelted NiCrBSi coatings were examined using optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, x-ray diffraction analysis, microhardness and wear testing. After wear tests, the surfaces of ...
Effect of boronizing on microstructure, high-temperature wear and corrosion behavior of additive manufactured Inconel 718
(Elsevier, 2022)
In this study, Ni-based Inconel 718 coatings were additively manufactured on the surface of AISI H13 work tool steel by electro-spark deposition (ESD). Some of the electro-spark deposited samples were boronized at 1000 ? ...
Investigation of the Effect of Alkali Curing on the Strength Properties of GBFS-Added Composites
(American Society of Civil Engineers (ASCE), 2022)
Large amounts of waste products have been and most probably will continue to be produced with urbanization, industrialization, and technological developments. The study presented herein is devoted to using blast furnace ...
Low temperature thermoelectric properties of Na-substituted Bi2Ca2Co2Oy ceramics fabricated via LFZ technique
(Elsevier, 2022)
In this work, Bi2Ca2-xNaxCo2Oy with x = 0.0, 0.05, 0.10, and 0.125 thermoelectric ceramic materials have been produced by the classical solid-state route, followed by texturing through the laser floating zone (LFZ) method. ...
Industrial scale extrusion performance of cryogenically processed DIN 100 Cr6 and DIN 21NiCrMo2 steels
(CSIC Consejo Superior de Investigaciones Cientificas, 2022)
The effects of diferent heat and cryogenic (sub-zero) treatment parameters such as temperature and holding time on the microstructure (amount of retained austenite) and hardness of extrusion molds produced from the 21NiCrMo2 ...
A new approach to improve some properties of wire arc additively manufactured stainless steel components: Simultaneous homogenization and boriding
(Elsevier, 2023)
Arc-directed energy deposition (Arc-DED), also commonly referred to as wire arc additive manufacturing (WAAM), is a cost-effective 3D metal additive manufacturing process in which large metallic parts can be produced due ...
Effect of powder-pack aluminizing on microstructure and oxidation resistance of wire arc additively manufactured stainless steels
(Elsevier, 2023)
This study investigated the effect of powder-pack aluminizing treatment on the high-temperature oxidation of ER307 stainless steel components fabricated by wire arc additive manufacturing (WAAM) during isothermal oxidation ...
