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 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 ...
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 ...
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 ...
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 ...
Comparative experimental study on the modification of microstructural and mechanical properties of friction stir welded and gas metal arc welded EN AW-6061 O aluminum alloys by post-weld heat treatment
(Wiley-VCH Verlag, 2018)
In this paper, the effects of post-weld heat treatment on modification of microstructures and mechanical properties of friction stir welded and gas metal arc welded AA6061-O plates were compared with each other. Gas metal ...
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 ...
Characterization and wear behavior of TiBC coatings formed by thermoreactive diffusion technique on AISI D6 steel
(Elsevier, 2020)
A two-step Thermo reactive diffusion processes (including an initial titatinizing step followed by boronizing) is proposed in order to obtain superhard complex TiBC coating layer on AISI D6 steel. Microstructural ...
