A new approach to sintering and boriding of steels "Boro-sintering": Formation, microstructure and wear behaviors
(Elsevier, 2020)
In this study, sintering and boriding methods are applied as a single step, and it is aimed to gain time and economic advantage. For this purpose, powder mixtures prepared in suitable compositions were subjected to sintering ...
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 ...
Effect of Different Arc Welding Processes on the Metallurgical and Mechanical Properties of Ramor 500 Armor Steel
(Asme, 2020)
In the present study, Ramor 500 armor steel plates were automatically welded using cold metal transfer arc welding (CMT), gas metal arc welding (GMAW), and hybrid plasma arc welding (HPAW) methods. To investigate the effects ...
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 ...
Mechanical properties of friction stir welded St 37 and St 44 steel joints
(Carl Hanser Verlag, 2018)
In this study, the weldability of lower strength St 37 grade steel plate with a higher strength steel plate (i. e., St 44) using the friction stir welding technique has been studied. St 37 grade steel sheets are widely ...
Friction stir welding/processing of metals and alloys: A comprehensive review on microstructural evolution
(Elsevier, 2021)
The unique combination of very large strains, high temperatures and high strain rates inherent to friction stir welding (FSW) and friction stir processing (FSP) and their dependency on the processing parameters provides ...
Microstructure and mechanical properties of borided CoCrFeNiAl0.25Ti0.5 high entropy alloy produced by powder metallurgy
(Elsevier, 2021)
CoCrFeNiAl0.25Ti0.5 high entropy alloy alloys (HEA), produced by powder metallurgy were subjected to boriding to improve their mechanical properties. Sintering was carried out at 1200 degrees C for 2 h in Ar, and boriding ...
Microstructure, some mechanical properties and tribocorrosion wear behavior of boronized Al0.07Co1.26Cr1.80Fe1.42Mn1.35Ni1.10 high entropy alloy
(Elsevier, 2021)
High-entropy alloys (HEAs) with face-centered cubic (FCC) structures exhibit high toughness and corrosion resistance, but their average strengths and relatively low wear resistance can limit their engineering ap-plications. ...
Effect of Cr Addition on Properties and Tribological Behavior at Elevated Temperature of Boride Layers Grown on Borosintered Powder Metallurgy Alloys
(Korean Institute of Metals and Materials, 2022)
This study focused on chromium addition (0 wt%, 3 wt%, 6 wt%, 9 wt% and 12 wt%) on the boride layer formation, microhardness, fracture toughness and elevated temperature friction and wear behaviour of alloys formed by ...
