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 ...
Investigation of microstructure and mechanical properties of friction stir welded dissimilar St37/St52 joints
(Institute of Physics Publishing, 2019)
Although friction stir welding (FSW) has widely been applied to aluminum alloys in several industries over the past three decades, it is not yet used in industry for joining of steels. The aim of this study is to characterize ...
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 Resistance of AISI H13 Hot-Work Tool Steel with Borided B4C Powders
(Korean Institute of Metals and Materials, 2019)
Abstract: In this study, the surface of AISI H13 steel was borided with powder blends of B4C and NaBF4 using the powder-pack method at 800, 900 and 1000 °C for 2, 4 and 6 h. The structural and mechanical characteristics ...
Properties and High Temperature Dry Sliding Wear Behavior of Boronized Inconel 718
(Springer, 2020)
Silicide-free boride layers were grown on Inconel 718 Ni-based superalloy surface at 850 degrees C, 950 degrees C, and 1050 degrees C for 2, 4, 6 hour by the powder pack-boronizing process using nano-sized B4C powders. The ...
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, ...
CO2-induced mechanical behaviour of Hawkesbury sandstone in the Gosford basin: An experimental study
(Elsevier, 2015)
Carbon dioxide (CO2) sequestered in saline aquifers undergoes a variety of chemically-coupled mechanical effects, which may cause CO2-induced mechanical changes and time-dependent reservoir deformation. This paper investigates ...
Mechanical Properties and Corrosion Resistance of Borosintered Distaloy Steels
(Springer, 2020)
Distaloy SA is a sponge iron powder (nominal composition: Fe-1.75Ni-1.5Cu-0.5Mo) widely used in the production of powder metallurgy (P/M) parts in the automotive industry. In this study, Distaloy SA powders were sintered ...
Properties and tribological performance of ceramic-base chromium and vanadium carbide composite coatings
(Elsevier, 2019)
In the current study, the surface of AISI D2 steel was coated with the powder blends of ferro-vanadium (Fe-V) and ferro-chromium (Fe-Cr). The coatings were performed using a thermo-reactive diffusion (TRD) treatment by the ...
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 ...
