Enhanced strength in Co-free Ni47.5-xFe25Cr25AlxTi2.5 high entropy alloys via introducing dual precipitates

open access: yesJournal of Materials Research and Technology, 2023
Synergistic strengthening mechanisms (e.g. solid solution strengthening, grain/twin boundary strengthening, dislocation strengthening, and precipitation strengthening) have been shown to effectively achieve a balance between strength and ductility of ...

Thermal and solute diffusion in α-Mg dendrite growth of Mg-5wt.%Zn alloy: A phase-field study

open access: yesJournal of Materials Research and Technology, 2023
Thermal and solute diffusion plays an important role in α-Mg dendrite growth, the diffusion mechanism of which is still unclear. Here, thermal and solute diffusion in α-Mg dendrite growth of Mg-5wt.%Zn alloy under non-isothermal solidification were ...

Elevated-temperature impact toughness of Mg–(Gd, Y)–Zr alloy [PDF]

open access: yes, 2013
The Charpy impact results for Mg–10Gd–3Y–0.5Zr and Mg–11Y–5Gd–2Zn–0.5Zr alloys at various temperatures showed that Mg–10Gd–3Y–0.5Zr was more sensitive to temperature. The increase in impact toughness with temperature was related to the blunt crack-tip at

The Influence of Alloy Composition and Liquid Phase on Foaming of Al−Si−Mg Alloys [PDF]

open access: yes, 2020
The foaming behaviour of aluminium alloys processed by the powder compaction technique depends crucially on the exact alloy composition. The AlSi8Mg4 alloy has been in use for a decade now, and it has been claimed that this composition lies in an “island

Microstructure of severely deformed metals from X-ray line profile analysis [PDF]

open access: yes, 2006
Two essentially different materials, cubic Ti(49.8)Ni(50.2) shape memory alloy and hexagonal AZ91 Mg alloy, were deformed by equal channel angular pressing (ECAP).

Anodic oxidation of Mg–Cu and Mg–Zn alloys

open access: yesElectrochimica Acta, 2004
Metastable, solid–solution Mg-0.8 at.% Cu and Mg-1.4 at.% Zn alloys have been anodized up to 250 V at 10 mA cm−2 in an alkaline phosphate electrolyte at 293 K in order to investigate the enriching of alloying elements beneath the anodic films. Rutherford backscattering spectroscopy (RBS) revealed enrichments to about 4.1×1015 Cu atoms cm−2 and 5.2×1015

Twinning-mediated formability in Mg alloys [PDF]

open access: yesScientific Reports, 2016
AbstractMg alloys are promising candidates for automotive applications due to their low density and high specific strength. However, their widespread applications have not been realized mainly because of poor formability at room temperature, arising from limited number of active deformation systems and strong basal texture.

Optimizing solidification dendrites and process parameters for laser powder bed fusion additive manufacturing of GH3536 superalloy by finite volume and phase-field method

open access: yesJournal of Materials Research and Technology, 2023
Investigating the surface morphology and microstructure of laser powder bed fusion (L-PBF) in solidification and optimizing process parameters is crucial for improving the accuracy and performance of cladding parts of GH3536 superalloy.
