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 ...
Microstructural and Mechanical Properties of Friction Stir Welded Nickel-Aluminum Bronze (NAB) Alloy
(Springer, 2016)
In this study, the applicability of friction stir welding to cast NAB alloy (i.e., C95800) with a thickness of 9 mm has been investigated. The joint performance was determined by conducting optical microscopy, microhardness ...
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 ...
TTribocorrosion behavior of boronized Co1.19Cr1.86Fe1.30Mn1.39Ni1.05Al0.17B0.04 high entropy alloy
(Elsevier, 2021)
Boride layers were grown on the surface of a Co1.19Cr1.86Fe1.30Mn1.39Ni1.05Al0.17B0.04 high-entropy alloy (HEA) by boronizing at temperatures of 900, 950 and 1000 degrees C for 4 h using nanosized boronizing powders. ...
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 ...
Boron nitride nanosheet-reinforced WNiCoFeCr high-entropy alloys: the role of B4C on the structural, physical, mechanical, and radiological shielding properties
(Springer, 2022)
The synthesis and extensive characterization of newly developed boron nitride nanosheet (BNNSs)-reinforced WNiCoFeCr high-entropy alloys (HEAs) are presented. The influence of B4C on the structural, physical, mechanical, ...
Effect of the boriding environment on the wear response of laser-clad AlCoCrFeNi high entropy alloy coatings
(Elsevier, 2022)
Laser-clad AlCrFeCoNi high entropy alloy (HEA) coatings, produced on the surface of AISI 316 L stainless steel, were pack-borided at 1000 °C for 4 h in open air, high-purity Ar and vacuum environments. The HEA, which had ...
Characterization of electrodeposited Ni-Cr/hBN composite coatings
(Elsevier, 2020)
In this study, NieCr/hBN composite coatings with different hBN content were deposited on AISI 1040mild carbon steel using electrodeposition. The coatings were characterized using scanning electronmicroscopy (SEM), energy ...
Microstructural characterization, boriding kinetics and tribo-wear behavior of borided Fe-based A286 superalloy
(Elsevier, 2022)
Iron-based superalloys are alloys produced for use in corrosive environments as an alternative to high-cost nickel-based superalloys. However, their average strength and hardness, attributed to their austenitic structures, ...
