An Alternative Approach to Study Photo-catalytic Behavior of TiO2 Using Synchrotron-Based Advanced Spectroscopic Techniques
Journal of Materials Engineering and Performance - Tập 32 - Trang 10391-10401 - 2023
Titanium oxide (TiO2)-based nanoparticles have grabbed immense attention for its
application as photo-catalyst in numerous fields of research like
photo-catalytic treatment of wastewater, water splitting and photo-catalytic
degradation of organic pollutants, etc. The current study utilizes
synchrotron-based x-ray diffraction (XRD), energy-dispersive Spectroscopy (EDX),
high-resolution scanning ele...
Development and performance of new hard and wear-resistant engineering materials
Journal of Materials Engineering and Performance - Tập 6 - Trang 749-756 - 1997
Wear is a major problem in many industrial applications, and the development of
wear-resistant materials is therefore both a technical and an economic
advantage. Iron-base composites bring new possibilities into the production of
wear-resistant materials because of their high hardness and sufficient fracture
toughness. They are suitable replacements for the conventional WC/Co cermets
owing to thei...
Effect of Chloride Ion on the Corrosion Behavior of 316L Stainless Steels in Hydrofluoric Acid Solution
Journal of Materials Engineering and Performance - - Trang 1-14 - 2023
In this study, the corrosion behavior of 316L stainless steel (SS) in
hydrofluoric acid and chloride-containing hydrofluoric acid solutions were
investigated. The immersion results show that the addition of chloride ions
yields a tremendous improvement in corrosion resistance. The corrosion rate of
316L SS remarkably reduces from 68.80 to 0.48 mm/a while adding 1 M chloride
ions into 23 M hydroflu...
Impact Energy of Functionally Graded Steels in Crack Arrester Configuration
Journal of Materials Engineering and Performance - Tập 19 - Trang 1058-1064 - 2009
Charpy impact energy of functionally graded steels produced by electroslag
remelting composed of graded ferrite and austenite layers together with bainite
or martensite intermediate layer in the form of crack arrester configuration has
been investigated. The results obtained in the present study indicate that the
notch tip position with respect to bainite or martensite layer significantly
affects ...
Modification of Microstructure and Mechanical Properties of AA6082/ZrB2 Processed by Multipass Friction Stir Processing
Journal of Materials Engineering and Performance - Tập 32 - Trang 285-295 - 2022
The present work accomplished homogenously disseminated ZrB2 reinforcement
particles and very fine grain structure by multipass friction stir processing
(MPFSP) of AA6082. They observed the influence of reinforcement particle ZrB2 on
the microstructure and tensile properties of the MPFSP. The coarse dendrite
structure of the base material AA6082 was studied using ZrB2 nanoparticles. The
MPFSP/ZrB2...
Constitutive Modeling of Hot Deformation Behavior of High-Strength Armor Steel
Journal of Materials Engineering and Performance - Tập 25 - Trang 1829-1838 - 2016
The hot isothermal compression tests of high-strength armor steel under a wide
range of deformation temperatures (1100-1250 °C) and strain rates of (0.001-1/s)
were performed. Based on the experimental data, constitutive models were
established using the original Johnson-Cook (JC) model, modified JC model, and
strain-compensated Arrhenius model, respectively. The modified JC model
considers the co...
Influence of Heat Treatment on the Microstructure and Corrosion Behavior of Thixo-cast Mg-Y-Nd-Zr
Journal of Materials Engineering and Performance - Tập 29 - Trang 6181-6195 - 2020
The influence of semisolid metal processing (SSM, also called thixoforming) and
T6 heat treatment (HT) on the microstructure and corrosion behavior in chlorides
of Mg-Y-Nd-Zr (WE43B) magnesium alloy was investigated. The as-cast
microstructure is composed of α-Mg grains with the size of 52.8 ± 1.9 μm
surrounded by eutectic precipitations enriched in rare-earth elements (Y, Nd).
The thixo-cast micr...
Effects of Oxide-Modified Spherical ZnO on Electrical Properties of Ag/ZnO Electrical Contact Material
Journal of Materials Engineering and Performance - Tập 25 Số 9 - Trang 3662-3671 - 2016
Novel Investigation on Nanostructured Multilayer and Functionally Graded Ni-P Electroless Coatings on Stainless Steel
Journal of Materials Engineering and Performance - Tập 24 - Trang 2373-2381 - 2015
In this study, step-wise multilayer and functionally graded Ni-P coatings were
deposited with electroless in which the content of phosphorus and nickel would
be changed gradually and step-wise through the thickness of the coatings,
respectively. To compare the properties of these coatings with Ni-P single-layer
coatings, three types of coatings with different phosphorus contents were
deposited. He...
Effect of Ho Content and Heat Treatment on the Corrosion Resistance of Mg-xHo-3Sm-0.5Zr Alloy
Journal of Materials Engineering and Performance - Tập 32 - Trang 7785-7795 - 2022
The corrosion resistance of as-cast Mg-xHo-3Sm-0.5Zr, solid solution and aged
Mg-8Ho-3Sm-0.5Zr alloys was studied by electrochemical experiments, weight loss
tests and microstructure analysis. The results showed that adding a proper
amount of Ho to the as-cast alloy can refine the grain size. Furthermore, Ho can
promote the precipitation of the Mg41Sm5 phase and form a new Mg24Ho5 phase. The
Mg-8H...
