Precipitation Strengthening of a Mg-Zn Alloy in Tension and Compression

2014
The effectiveness of precipitation strengthening against slip and twinning was quantified for a Mg-Zn containing different distributions of rod-shaped s 1 ′ precipitates. Tensile and compressive testing was carried out on identically heat-treated samples to determine the effect of a well-characterised particle distribution on each deformation mode ...

Improvement of mechanical properties of a nanoaluminium alloy by precipitate strengthening

Archives of Metallurgy and Materials, 2012
In the present study, severe plastic deformation (SPD) processing was combined with pre- and post processing heat treatment to investigate the possibility of synergic grain size and precipitation strengthening. Samples of 7475 alloy were solution heat treated and water quenched prior to hydrostatic extrusion (HE) which resulted in a grain refinement by

Specific Response of Additively Manufactured AlSi9Cu3Fe Alloy to Precipitation Strengthening

Metals and Materials International, 2019
The additive manufacturing of Al–Si–Cu/Mg alloys along with their precipitation strengthening represents a promising option of producing high-strength complex-shaped light-weight components for special applications in automotive or aerospace.

Precipitation strengthening of binary AlLi alloys by δ′ precipitates

Materials Science and Engineering: A, 1988
Abstract The published data on the strengthening of binary AlLi alloys by δ′ precipitates are analyzed according to a recent version of the theory of order strengthening. The results are found to agree with the data provided that the antiphase boundary energy γapb on {111} is assigned a value in the range 0.140–0.160 J m−2.

Precipitate strengthening mechanisms in magnesium zinc alloy single crystals

Journal of Materials Science, 1969
The mechanical behaviour of Mg-5.1 wt % Zn alloy single crystals was studied in the 4.2 to 300° K temperature range. Quenched crystals have activation energies and volumes best associated with the cutting of small clusters of Zn atoms by dislocations.

Effect of Er additions on the precipitation strengthening of Al–Hf alloys

Scripta Materialia, 2014
Precipitation strengthening was investigated in dilute Al–Er, Al–Hf and Al–Er–Hf alloys. Combined addition of 0.045 at.% Er and 0.18 at.% Hf in Al gives a maximum hardness of 640 MPa, which is significantly higher than that of the Al–0.18Hf and Al–0.045Er alloys.
