Precipitation behaviors of multi-scale precipitation strengthened Al–Mg–Si–Cu–Zn alloys controlled by Mg content

Journal of Materials Research and Technology, 2021
In this paper, the effect of the Mg content and the precipitation behaviors in Al–Mg–Si–Cu–Zn alloys is reported. Also, the low strength of 6xxx aluminum alloys is improved by high alloying degree, in which the Mg and Si contents exceed the range of 6xxx

Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy [PDF]

Advanced Science
Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack initiation sites. In this work, we overturn this paradigm through atomic‐scale interfacial engineering, transforming brittle GB phases ...

Precipitate strengthening of pyramidal slip in Mg–Zn alloys [PDF]

Materials Science and Engineering: A, 2021
The mechanical properties of Mg-4wt.% Zn alloy single crystals along the [0001] orientation were measured through micropillar compression at 23C and 100C. Basal slip was dominant in the solution treated alloy, while pyramidal slip occurred in the precipitation hardened alloy. Pyramidal dislocations pass the precipitates by forming Orowan loops, leading

Precipitation Strengthening of Cu–Ni–Si Alloy [PDF]

Materials, 2020
The work examines the effect of rhenium addition on the structure and properties of Cu–2Ni–1Si alloys. The aim of this work was to answer the question of how the addition of rhenium will affect the strengthening mechanisms of rhenium-modified, saturated, plastically deformed and aged Cu–2Ni–1Si alloys.

Precipitation-strengthened austenitic Fe−Mn−Ti alloys [PDF]

Metallurgical Transactions A, 1979
The precipitation of the intermetallic compounds in the Fe-20 Mn-2 Ti and Fe-28 Mn-2 Ti alloy systems has been investigated over the temperature range 700 to 900/sup 0/C using hardness measurements, optical and scanning electron microscopy, and x-ray diffraction.

Compositional interpretation of high elasticity Cu–Ni–Sn alloys using cluster-plus-glue-atom model

Journal of Materials Research and Technology, 2022
The D022 or L12-γ′ phase strengthened Cu–Ni–Sn alloys possesses a characteristic microstructure, exhibiting the distribution of precipitated phase with smaller size on a spinodal decomposition structure, which leads to that the composition of the ...

Precipitation strengthening in an ultralight magnesium alloy [PDF]

Nature Communications, 2019
AbstractBody-centred cubic magnesium-lithium-aluminium-base alloys are the lightest of all the structural alloys, with recently developed alloy compositions showing a unique multi-dimensional property profile. By hitherto unrecognised mechanisms, such alloys also exhibit exceptional immediate strengthening after solution treatment and water quenching ...

Flat hardness distribution in AA6061 joints by linear friction welding

Scientific Reports, 2021
It is known that one of the main concerns associated with the conventional welding of precipitation-strengthened Al alloys is the formation of softening regions, resulting in the deterioration of mechanical properties.
