An Ab Initio Study of Connections between Tensorial Elastic Properties and Chemical Bonds in Sigma5(210) Grain Boundaries in Ni3Si
(2018-11-13)
Using quantum-mechanical methods we calculate and analyze (tensorial) anisotropic elastic properties of the ground-state configurations of interface states associated with Sigma5(210) grain boundaries (GBs) in cubic ...
Influence of Scanning Strategies on Processing of Aluminum Alloy EN AW 2618 Using Selective Laser Melting
(MDPI, 2018-02-14)
This paper deals with various selective laser melting (SLM) processing strategies for aluminum 2618 powder in order to get material densities and properties close to conventionally-produced, high-strength 2618 alloy. To ...
Influence of Cold-Sprayed, Warm-Sprayed and Plasma Sprayed Layers Deposition on Fatigue Properties of Steel Specimens
(Springer, 2015-03-10)
Titanium powder was deposited onto steel specimens using four thermal spray technologies: plasma spray, low-pressure cold spray, portable cold spray, and warm spray. The specimens were then subjected to strain controlled ...
Influence of Processing Techniques on Microstructure and Mechanical Properties of a Biodegradable Mg-3Zn-2Ca Alloy
(MDPI, 2016-10-28)
New Mg-3Zn-2Ca magnesium alloy was prepared using different processing techniques: gravity casting as well as squeeze casting in liquid and semisolid states. Materials were further thermally treated; thermal treatment of ...
Automated calibration of advanced cyclic plasticity model parameters with sensitivity analysis for aluminium alloy 2024-T351
(SAGE Publications, 2019-03-18)
The plasticity models in finite element codes are often not able to describe the cyclic plasticity phenomena satisfactorily. Developing a user-defined material model is a demanding process, challenging especially for ...
Elastic and Plastic Behavior of the QE22 Magnesium Alloy Reinforced with Short Saffil Fibers and SiC Particles
(MDPI AG, 2018-02-15)
Magnesium alloy QE22 (nominal composition 2 wt % Ag, 2 wt % mixture of rare earth elements, balance Mg) was reinforced with 5 vol % Saffil fibers and 15 vol % SiC particles. The hybrid composite was prepared via the squeeze ...
Modification of Plasma Sprayed TiO2 Coatings Characteristics via Controlling the In-flight Temperature and Velocity of the Powder Particles
(Springer, 2014-08-27)
The study presents a comprehensive research on the plasma spray fabrication of TiO2 coatings with microstructural properties adjustable via controlling the respective in-flight properties of the feedstock particles. The ...
Influence of plasma electrolytic oxidation on fatigue performance of AZ61 magnesium alloy
(Elsevier, 2014-05-01)
The effect of plasma electrolytic oxidation (PEO) on the fatigue of AZ61 magnesium alloy has been investigated under high cycle conditions in air and 3.5% NaCl solution. PEOemployed an alkaline pyrophosphate-silicate-fluoride ...
Oxidation Performance of Cold Spray Ti-Al Barrier Coated gamma-TiAl Intermetallic Substrates
(Elsevier, 2015-04-04)
Four blends of Al powder containing different amounts of Ti were deposited onto Ti-46Al-7Nb substrates as oxidation-protection layers using low-pressure cold spray. The coating morphology and chemical composition were ...
Master Sintering Curve - A Practical Approach to its Construction
(International Institute for the Science of Sintering, 2010-04-01)
A practical method for the construction of MSC is presented in the paper. With the help of a few dilatometric sintering experiments the newly developed software calculates MSC and finds the optimal activation energy of a ...
