Cryogenic tensile behavior of laser additive manufactured CoCrFeMnNi high entropy alloys
In the present work the microstructural evolution, tensile properties, and deformation behavior of additively manufactured equiatomic CoCrFeMnNi high entropy alloy (HEA) were investigated at a cryogenic temperature (77 K). Metal additive manufacturing components are known to have exceptional yield strength, without compromising ductility. Here, las...
Microstructure tailoring by manipulating chemical composition in novel CoNiMnCrAl high-entropy alloys
One of the most important dilemmas in materials science is to overcome the strength-ductility trade-off. There is an increasing trend toward designing alloys with strong precipitates in order to tackle this issue. The brittle sigma phase, a prevalent precipitate in high-entropy alloys, is responsible for the deterioration of the mechanical properti...
Investigation of the Dynamic Strain Aging Effect in Austenitic Weld Metals by 3D-DIC
Austenitic stainless steels similar to type AISI 316L are widely used structural materials in current and future nuclear reactors. Careful development and characterization of these materials and their welds is needed to verify the structural integrity of large-scale multicomponent structures. Understanding the local deformation behavior in heteroge...
Effects of asymmetric basal texture on the stretchability and the microstructure variations for the rolled ZK60 magnesiu...
© 2022 Elsevier B.V.In order to clarify the asymmetric basal texture effects on the stretchability and the microstructure variations of magnesium alloy sheet, two kinds of stretch forming samples were extracted along the rolling direction (RD) and the transverse direction (TD) from ZK60 magnesium alloy sheet with asymmetric basal texture. Their var...
MOFs for long-term gas storage : exploiting kinetic trapping in ZIF-8 for on-demand and stimuli-controlled gas release
In this study, we investigate the potential of metal-organic frameworks (MOFs) for long-term gas storage under ambient conditions. Specifically, we selected a MOF ZIF-8 (with a 0.34 nm large pore aperture), which exhibits a temperature- and pressure-regulated gating effect, and loaded it with sulphur hexafluoride (with a kinetic diameter of 0.55 nm...
Exploiting satellite SAR for archaeological prospection and heritage site protection
Optical and Synthetic Aperture Radar (SAR) remote sensing has a long history of use and reached a good level of maturity in archaeological and cultural heritage applications, yet further advances are viable through the exploitation of novel sensor data and imaging modes, big data and high-performance computing, advanced and automated analysis metho...
